How to Delete WordPress Theme

A WordPress theme controls the appearance and layout of your WordPress site. It includes template files that determine how your content is displayed. Many themes come with additional functionality like menus, widgets, and more.

When you first install WordPress, it includes the default theme called Twenty Twenty-One. You can then install themes from the WordPress theme directory or purchase premium themes for more design options.

Over time, you may accumulate themes that you no longer need. Deleting unused themes can help free up space on your web server and slightly improve your site’s performance.

When Should You Delete a WordPress Theme?

Here are some common reasons to remove a WordPress theme:

  • You have activated a new theme: If you are no longer using a theme, it’s best to delete it. Just make sure your new theme is fully set up first.
  • It’s an unused theme: Get rid of themes you installed to test out but decided not to use long-term.
  • It’s slowing your site down: Too many unused themes can negatively impact performance.
  • You’re removing a site: Delete all files when deleting a WordPress site.

How to Delete a WordPress Theme

WordPress stores all uploaded themes in the /wp-content/themes/ directory on your server. To delete a theme, you simply need to remove its folder from this location.

There are a few ways to access these theme files:

Via the WordPress Dashboard

This is the easiest way to delete a theme if you have admin access:

  1. Log in to your WordPress dashboard
  2. Go to Appearance > Themes
  3. Hover over the theme you want to delete
  4. Click on Theme Details
  5. Click the Delete button to remove the files

Via FTP

If you have FTP details for your site’s server, you can directly access the theme folders:

  1. Connect to your site using an FTP client like FileZilla
  2. Navigate to the /wp-content/themes/ folder
  3. Right-click on the theme’s folder and select delete
  4. Confirm the folder removal

Via cPanel

If your WordPress site is hosted on a web server with cPanel, you can use the File Manager:

  1. Log in to your hosting cPanel
  2. Open the File Manager tool
  3. Browse to the /wp-content/themes/ folder
  4. Right-click on the theme you want to delete
  5. Click Delete and confirm the removal

Things to Check Before Deleting a Theme

Before getting rid of any theme files, it’s important to take a few precautions:

  • Make sure you have another theme activated first. If you delete the active theme, your site may break.
  • Consider backing up the theme folder before removing it permanently.
  • Check if the theme has a parent-child relationship. Some themes rely on their parent to function.

After Deleting a WordPress Theme

After removing a theme, check if it was integrated with other parts of your site:

  • Your media library may have unused images now. Remove any orphaned uploads.
  • Menus, widgets and other theme settings may need to be cleaned up or reset.
  • Test all site functionality to make sure everything still works properly.
  • Consider any additional WordPress performance optimization steps. Removing unused themes is just one way to help speed up your site.

Additional Tips for Managing WordPress Themes

Optimize Your Database After Theme Deletion

Deleting a theme often leaves behind residual data in your WordPress database, which can slow down your site. Use plugins like WP-Optimize or Advanced Database Cleaner to remove orphaned entries and improve your site’s performance.

Consider Lightweight Themes for Better Performance

When replacing a deleted theme, opt for lightweight and performance-focused themes like GeneratePress, Astra, or Kadence. These themes are designed with clean code and minimal bloat, ensuring faster load times and a better user experience.

Test Your Site Thoroughly

After deleting a theme, review your site for any broken links, missing images, or layout inconsistencies. Tools like Broken Link Checker can help identify and resolve such issues quickly.

Backup Regularly

Before making changes like deleting themes, always back up your site. Plugins such as UpdraftPlus or Duplicator make it easy to create a full backup of your WordPress installation, ensuring you can restore your site if needed.

FAQ

Can I delete the default WordPress theme?

Yes, but it’s recommended to keep at least one default theme (like Twenty Twenty-One) as a fallback. This ensures you have an active theme if something goes wrong with your current one.

What happens if I delete an active theme?

WordPress won’t allow you to delete an active theme. You’ll need to activate another theme before removing the one currently in use.

Are there security risks with unused themes?

Yes, unused themes that are outdated or no longer updated by developers can become security vulnerabilities. Hackers may exploit these to gain access to your site.

How do I clean up after deleting a theme?

After deletion, check for leftover files in the Media Library, unused widgets, and orphaned database entries. Use tools like database optimization plugins to ensure everything is tidy.

Can I recover a deleted theme?

If you’ve backed up your site before deletion, you can restore the theme from the backup. Without a backup, you’ll need to reinstall the theme manually.

By following these steps and best practices, you can maintain a secure, efficient, and well-organized WordPress site!
