Knowing how to deactivate a WordPress theme might seem like it's just about a single click, but the real expertise lies in understanding why and when to do it. It's a fundamental step in troubleshooting, a core part of any site redesign, and a key technique for sniffing out performance issues.
When and Why You Should Deactivate a WordPress Theme

Deactivating a WordPress theme isn’t just a task for developers; it’s a powerful diagnostic tool every site owner should have in their back pocket. While the idea might sound a bit drastic, it’s often the fastest way to get to the bottom of common—and frustrating—problems.
Think of it as a process of elimination. If a plugin feature suddenly stops working or your site crashes right after an update, a theme conflict is a very likely culprit. Temporarily switching to a default theme like Twenty Twenty-Four can instantly tell you if your theme is the source of the trouble.
Common Scenarios for Deactivation
The need to deactivate a theme pops up in a few common situations. Once you learn to recognize these, you can act decisively instead of losing hours searching for a more complicated fix.
You’ll want to consider deactivating your theme for:
- Troubleshooting Conflicts: This is the number one reason. If a specific function, like a Divi popup, suddenly breaks, activating a default theme helps you figure out if the problem is with your theme, a plugin, or WordPress itself.
- Fixing Critical Errors: The dreaded 'White Screen of Death' (WSOD) or a fatal error can often be traced back to a bad theme file or a botched update. Deactivating the theme via FTP is a common emergency procedure to get your site back online.
- Preparing for a Redesign: Before you can roll out a new design, you have to switch off the old one. If you're planning a major overhaul or bringing in a professional website design service, understanding this process is crucial for a smooth transition.
- Performance Benchmarking: To get a true baseline of your site's speed, deactivating a heavy, feature-packed theme is a must. This lets you measure your server performance and Core Web Vitals without the theme's code clouding the results.
Key Takeaway: Deactivating a theme is a standard diagnostic step, not a last resort. It empowers you to pinpoint conflicts, fix errors, and prepare for site changes with confidence.
By treating theme deactivation as a regular maintenance task rather than a catastrophe, you gain more control over your website. It’s a simple action that can save you a massive amount of time and frustration. The goal is to quickly find the root cause of a problem so you can get on with the right fix.
Essential Precautions Before Deactivating Your Theme
Before you even think about deactivating a theme in WordPress, it’s critical to pause and take some precautions. Jumping straight into deactivation on a live site without a safety net is like starting a major renovation without checking the building's foundation—things can go wrong fast, and the result can be a total collapse.
A full site backup is your absolute, non-negotiable first move. I'm not just talking about your posts and pages; a complete backup includes your WordPress files, plugins, and the all-important database where your settings and content actually live. Many hosting providers offer one-click backup tools, or you can use a trusted plugin like UpdraftPlus or Duplicator to create a complete restore point.
Having a fresh backup means that if anything goes sideways—like the dreaded White Screen of Death—you can restore your site to its previous state in minutes, not hours.
Your Pre-Deactivation Safety Checklist
Once you’ve got that backup stored somewhere safe, it’s time to run through a quick pre-flight checklist. For anyone making significant site changes, it’s always a good idea to follow a comprehensive website maintenance checklist to make sure all your bases are covered.
Here are the key safety steps I never skip:
- Use a Staging Environment: A staging site is a private clone of your live website. It's the perfect sandbox to deactivate themes, test new plugins, and break things without a single visitor ever knowing. This is by far the safest way to foresee any issues before they ever impact your business.
- Have a Default Theme Ready: Make sure a standard WordPress theme like Twenty Twenty-Four is installed. If you ever find yourself locked out and needing to rename your theme folder via FTP, WordPress needs a fallback theme to load. This simple step can be the key to getting your admin access back.
- Consider a Child Theme: If you've made any custom code modifications, they should always live in a child theme. The beauty of this is that deactivating a parent theme won't erase the customizations you've saved in its child, which will make your life much easier later on. If you're new to this, we have a complete walkthrough on how to create a Divi child theme.
Taking these few extra minutes for preparation is what separates a smooth troubleshooting session from a full-blown site emergency. With these precautions in place, you can move forward with confidence.
Deactivating a Theme Through the WordPress Dashboard
If your site is running smoothly and you have admin access, the simplest way to switch your theme is right through the WordPress dashboard. This is the standard, built-in method—no technical wizardry, file access, or database knowledge needed. It’s clean, instant, and completely reversible.
First things first, log into your WordPress admin area. In the left-hand navigation menu, find the Appearance section. Hover over it, and a submenu will pop up—from there, click on Themes.
You'll land on the main Themes screen, which shows every theme you have installed. Your active theme is always front and center, clearly marked. You might notice there's no "Deactivate" button on it. This is a common point of confusion for new users, but it's intentional.

The key takeaway is that you don't directly deactivate a theme in WordPress. Instead, you deactivate the current theme by activating a new one in its place.
Activating a New Theme to Deactivate the Old One
To do this, you need at least one other theme installed. It's a great practice to always keep a default WordPress theme like Twenty Twenty-Four on hand for exactly this reason.
Find the theme you want to switch to and hover your mouse over it. A button labeled Activate will appear.
Click that "Activate" button. Instantly, two things happen:
- WordPress makes the new theme the live, active one on your site's frontend.
- Your previous theme is automatically deactivated.
That’s all there is to it. You’ve now successfully deactivated a WordPress theme using the dashboard. No extra "deactivate" step is required.
What’s Happening Behind the Scenes? When you activate a new theme, WordPress just updates two rows in your site's
wp_optionsdatabase table—'template' and 'stylesheet'—to point to the new theme's folder. Your old theme’s files and settings remain untouched, just dormant.
Post-Activation Checks
After you activate the new theme, your site's appearance is going to change dramatically. The old theme's design, styling, and specific features are now gone from the public-facing side of your site.
It's a good idea to quickly run through a few checks:
- Menus: Your navigation menus might need to be reassigned to the new theme's menu locations. You can fix this under
Appearance > Menus. - Widgets: Widgets from your old theme will likely be moved to an "Inactive Widgets" area. You'll need to drag them back into the new theme’s sidebars or other widget-ready spots.
- Shortcodes: If your previous theme relied on a page builder or custom shortcodes, your content might now show those codes as plain text (e.g.,
[my_button]).
This dashboard method is by far the safest and most common way to switch themes, making it the perfect starting point for any site redesign or troubleshooting process.
Using FTP to Deactivate a Theme in an Emergency
What happens when your site is down and you can’t even log in? A bad theme update or a conflict can sometimes cause the dreaded White Screen of Death (WSOD), completely locking you out of your WordPress admin dashboard. In emergencies like this, the dashboard method is useless. You need a direct way to take back control.
This is where knowing how to use an FTP client or your web host's File Manager becomes an essential skill. By directly accessing your website's files on the server, you can manually deactivate a faulty theme and force WordPress to load a default one, instantly restoring your access.
Accessing Your Site Files
First, you need to connect to your server. You can do this with a dedicated FTP client like FileZilla or Cyberduck, or through the File Manager tool found in your hosting control panel (like cPanel or Plesk). Your hosting provider will give you the necessary FTP credentials—server address, username, and password—to get connected.
Once you’re in, you'll see all the files and folders that make up your WordPress installation. Your goal is to get to the themes folder.
- Look for the
public_htmlorwwwfolder, which is usually the root directory for your website. - Inside, find the
wp-contentfolder. This is where your themes, plugins, and media uploads are stored. - Finally, open the
themesfolder. Here, you'll see a separate folder for each theme you have installed.
Pro Tip: This method doesn't delete your theme. It simply takes it offline, keeping all its settings and files intact. You're just temporarily disabling it so you can get back into your WordPress admin area to figure out what went wrong.
Renaming the Theme Folder to Force Deactivation
Now for the critical step. Inside the themes directory, find the folder of your currently active theme. For example, if you're using Divi, the folder will be named divi.
Right-click on the problematic theme's folder and select the Rename option. You don't need a complicated new name; something simple will do. I often just add -off or -disabled to the end.
For example, you would rename:
divitodivi-offavadatoavada-disabled
By renaming the folder, you've made it impossible for WordPress to find the active theme's files. When this happens, WordPress has a built-in failsafe: it automatically falls back and activates a default theme, like Twenty Twenty-Four. This action breaks the error loop and should immediately restore access to your admin login page.
After renaming the folder, try logging into your WordPress dashboard. Once you’re in, you can investigate the issue, roll back the theme to a previous version, or contact the theme developer for support. This is a powerful troubleshooting technique that works similarly to how you would diagnose plugin conflicts. If you're interested in that process, you can read our guide on how to install a WordPress plugin, which covers related management skills. Once the underlying issue is fixed, just rename the theme folder back to its original name and reactivate it from the dashboard.
While the dashboard and FTP methods will get you out of a jam most of the time, developers and power users often need faster, more powerful ways to manage themes. This is especially true when you're working across multiple sites or in highly restricted server environments.
That's where the command line and direct database editing come into play. These are the "break glass in case of emergency" tools for when nothing else works.
Deactivating a Theme with WP-CLI
If you’re comfortable with a terminal, the WordPress Command-Line Interface (WP-CLI) is an absolute game-changer. Forget clicking through menus—you can switch themes with a single command. For anyone managing client sites or performing routine maintenance at scale, it's the very definition of efficiency.
Just SSH into your server, navigate to your WordPress root directory, and you can instantly get a list of all installed themes.
To see what's on your site, run this command:wp theme list
This spits out a clean table showing every theme's name, its status (active/inactive), available updates, and version. From there, activating a different theme is a breeze, which automatically deactivates the current one.
To switch to the default Twenty Twenty-Four theme, for example, you’d just type:wp theme activate twentytwentyfour
And that's it. Theme switched. There is no faster way to do it. This method is perfect for headless setups or when you're working through an SSH-only connection without a graphical interface.
Manually Deactivating via the Database
In very rare cases, you might find yourself locked out of both the admin dashboard and FTP/SSH access. If you can still get into the database (usually via a tool like phpMyAdmin), you can force a theme deactivation by editing the database directly.
Critical Warning: This is a high-risk maneuver. Editing your database directly can permanently break your site if you make a mistake. Always create a full database backup before you begin, and only proceed if you're confident you know what you're doing.
Here’s the emergency procedure:
- Open phpMyAdmin and select your WordPress database.
- Find and open the
wp_optionstable (note: your table prefix might be different, likewp_). - Locate the rows where the
option_nameis template and stylesheet. You may need to browse through a few pages to find them. - Edit the
option_valuefor both of those rows. Change it to the folder name of a default theme you know is installed, liketwentytwentyfour.
This action manually tells WordPress which theme to load, completely bypassing whatever faulty theme was causing the lockout.
So, with four different methods available, which one should you choose? It really depends on your access and comfort level.
Which Deactivation Method Should You Use?
Here's a quick breakdown to help you decide which path to take, whether you're in a full-blown emergency or just making a routine switch.
| Method | Best For | Required Tools | Difficulty |
|---|---|---|---|
| WP Admin | Everyday theme switching when everything is working. | WordPress admin access | Easy |
| FTP/SFTP | When you’re locked out by the White Screen of Death. | FTP/SFTP client (e.g., FileZilla) | Medium |
| WP-CLI | Developers and power users needing a fast, scalable solution. | SSH access, WP-CLI installed | Advanced |
| Database | Last-resort emergencies when you have no admin or file access. | phpMyAdmin or database access | Expert |
Think of it as a hierarchy. Always start with the simplest method (WP Admin). If that fails, move down the list to FTP, then WP-CLI, and only touch the database as a final, last-ditch effort.
This decision tree gives you a quick visual guide for choosing your deactivation method when you're in a hurry and need a solution, fast.

As you can see, the first question is always whether you're locked out of your site. Answering that simple question will point you directly to the most appropriate and effective solution for your situation.
What Happens After Deactivating Your WordPress Theme

The moment you deactivate your WordPress theme and switch to a new one can be pretty jarring. One second you have a beautifully designed website, and the next, it looks like a jumbled mess of text and broken elements. Don't panic—this is totally normal, especially if you're moving away from a feature-rich theme.
Many complex themes rely on proprietary shortcodes to build layouts and add special features. When you deactivate that theme, WordPress no longer knows how to interpret those shortcodes, so it just displays the raw text (like ) on the page. Your content isn't gone; it's just temporarily unreadable.
Your Post-Deactivation Cleanup Checklist
Navigating the aftermath is all about running through a quick, structured cleanup process. Certain elements almost always get shuffled around during a theme switch, and knowing where to look is half the battle. This turns what looks like chaos into a manageable to-do list.
Here are your immediate priorities:
- Reassigning Menus: Your navigation menus are still saved, but the new theme has no idea where to display them. You'll need to go to
Appearance > Menusand re-assign your primary and footer menus to the new theme’s designated locations. - Checking Widgets: Widgets from your old theme have likely been moved to an "Inactive Widgets" area. Your job is to drag and drop them back into the new theme's available sidebars, footers, or other widget-ready sections.
- Reviewing Shortcodes: If your pages are now littered with leftover shortcodes, you'll need a plan. For anyone switching away from Divi, installing the standalone Divi Builder plugin can often preserve your layouts even without the full Divi theme active.
The most important thing to remember is that your core content—all your posts, pages, and images—is safely stored in the database. A theme change primarily affects presentation and styling, not the data itself.
Once you’ve sorted out the basics, it’s a good idea to check any plugin-specific settings. For example, an e-commerce plugin like WooCommerce might have display settings that were tied to your old theme. It's also a great time to re-evaluate your homepage settings; you can get more tips in our guide on how to change the front page in WordPress. By working through this checklist systematically, you can ensure a much smoother and more organized transition.
Frequently Asked Questions About Deactivating Themes
Even with the steps laid out, you might still have a few lingering questions about what really happens when you deactivate a WordPress theme. Let's tackle some of the most common concerns I hear from users.
Will I Lose My Content If I Deactivate My Theme?
The short answer is no, you won't lose your core content. All of your pages, blog posts, images, and user data are safely tucked away in your WordPress database. Your theme is just the "skin" that styles all that data.
However, you will lose any content or settings that are specific to that theme. For example, if you built pages using a theme's integrated page builder, those layouts will likely break and appear as a jumble of shortcodes. You'd need to reactivate the theme or use a special plugin to get that content to display correctly again.
Can I Delete a Theme Instead of Deactivating It?
You can, but I almost never recommend it as the first step. Think of deactivating as a temporary and completely reversible action. Deleting, on the other hand, permanently removes the theme's files from your server. It's a much bigger commitment.
The only time you should consider deleting a theme is when you are 100% certain you will never use it again and you have a fresh, complete backup of your site. Otherwise, just leave the deactivated theme installed. It doesn't hurt anything.
What Is the Safest Way to Deactivate a Theme?
The safest method, hands down, is to use a staging site. A staging environment is a private clone of your live website. It's the perfect sandbox to deactivate themes, test new plugins, or troubleshoot errors without any of your visitors ever knowing something is happening behind the scenes.
If you absolutely have to work on your live site, the very first thing you must do is take a full backup. This gives you a reliable restore point to fall back on if the deactivation process goes sideways. No exceptions.
