How to Delete Themes from WordPress: A Step-By-Step Guide
Deleting unwanted WordPress themes is an essential housekeeping task for website owners. Removing unused themes helps keep your website secure, organized, and running smoothly. Whether you’re looking to free up space, tidy your dashboard, or improve site performance, knowing how to properly delete WordPress themes is a skill every user should master. This guide will walk you through everything you need to know, from understanding why deletion matters to practical, step-by-step methods—no matter your technical background.
Why Delete WordPress Themes?
You may wonder why it’s necessary to remove themes instead of just leaving them inactive. Here are some compelling reasons:
- Enhanced Security: Unused themes can still house vulnerabilities that hackers exploit. Deleting them reduces potential risks.
- Improved Performance: Although inactive themes don’t affect your website’s speed directly, cleaning up your site makes it easier to manage and update.
- Simplified Management: A clutter-free dashboard helps you track updates, make changes, and back up your site efficiently.
- Save Server Space: Every theme installed on your site uses valuable server storage.
What to Know Before Deleting a Theme
Before hitting the delete button, consider the following:
- Make Sure the Theme is Not Active: You cannot delete the currently active theme. Switch to another theme first if necessary.
- Take a Backup: Although deleting a theme shouldn’t affect your site’s content, it’s smart to back up your WordPress site before making any significant changes.
- Child Themes: If you’re deleting a parent theme and have a related child theme, double-check that you’re not affecting your live design.
- Saved Customizations: Custom code edits or files within the theme folder will be deleted. Save a copy if you need to reference customizations later.
Step-by-Step: How to Delete a WordPress Theme
Let’s break down various methods you can use—each is beginner-friendly and safe if you follow the instructions.
1. Deleting a Theme via the WordPress Dashboard (Easiest Way)
This is the simplest and most common method, recommended for most users.
Step 1: Access the Themes Page
- Log in to your WordPress admin dashboard.
- Navigate to Appearance > Themes.
Step 2: Select the Theme to Delete
- Locate the theme you wish to remove (make sure it isn’t currently active).
- Click on the theme’s thumbnail or hover over it.
- You will see a “Theme Details” button—click it.
Step 3: Delete the Theme
- In the lower right corner of the theme details window, look for the Delete button.
- Click Delete.
- When prompted, confirm deletion.
That’s it! The theme will be permanently removed from your site.
2. Deleting a Theme Using FTP/SFTP
If you have trouble accessing your dashboard or prefer working with files directly, use this method.
Step 1: Connect to Your Site
- Use an FTP client (like FileZilla) or your hosting’s file manager.
- Log in with your credentials.
Step 2: Locate the Themes Folder
- Navigate to
/wp-content/themes/. - You will see a list of all installed themes.
Step 3: Delete the Unwanted Theme
- Find the folder that matches the theme you wish to remove.
- Right-click and select Delete (in FTP) or use your hosting control panel’s delete option.
Note
There’s no confirmation step here—make sure you’re deleting the correct theme folder.
3. Deleting a Theme Using WP-CLI (Command Line)
Advanced users can use WP-CLI, the WordPress command line interface.
Step 1: Open Your Command Line
- Connect to your website server with SSH.
Step 2: Check Installed Themes
- Enter:
wp theme list - This command shows all installed themes and their status.
Step 3: Delete the Theme
- Enter:
wp theme delete themename - Replace “themename” with the folder name of the theme you wish to remove.
4. Deleting Themes Through Hosting Control Panel
Some hosts provide a file manager in their dashboards.
Step 1: Log into Hosting Control Panel
- Go to your host’s dashboard and access the file manager.
Step 2: Navigate and Delete
- Browse to
/wp-content/themes/. - Select the theme folder you want to delete and use the delete function.
What Happens When You Delete a Theme?
- Files Removed: All theme files, templates, and customizations stored within that folder are erased.
- Site Remains Intact: Your posts, pages, plugins, and active theme are unaffected.
- No Rollback: Once deleted, the theme cannot be restored unless you re-upload it.
Therefore, always back up custom code or options stored within a theme’s folder.
Benefits of Removing Unused Themes
- Reduced Security Risks: Cyber attackers exploit outdated or unused files; removing them strengthens your site.
- Efficient Updates: Fewer themes mean fewer update notifications to sort through, allowing you to focus on maintaining your active setup.
- Tidier Site Management: Easier to navigate, especially for sites with multiple administrators or regular theme changes.
- Saves Space: Every MB counts, particularly on limited hosting plans.
Common Challenges When Deleting Themes
Deleting themes is generally flexible, but sometimes you might encounter:
- Permission Errors: Can’t delete via the dashboard? Try FTP or check file permissions.
- Child/Parent Theme Issues: Accidentally deleting a parent theme needed by an active child theme can break your site’s appearance.
- Locked-out Situations: Rare dashboard access issues can be resolved by using FTP or your hosting panel instead.
If you face problems, revert to your site backup or contact your hosting provider’s support.
Best Practices When Deleting WordPress Themes
Make the most of your theme management with these tips:
- Regular Review: Periodically check and remove unnecessary themes.
- Always Have a Backup: Consider full-site or database backups before deletions.
- Keep One Default Theme: Retain a default theme (like Twenty Twenty-One) as a fallback in case of active theme issues.
- Audit for Customizations: If you’ve edited theme files, copy those changes elsewhere before deleting.
Tips for Safe and Effective Theme Management
- Only install themes you’re either testing or actively using.
- Avoid leaving obsolete or unsupported themes installed.
- Update your active and default backup themes promptly.
- Use child themes for customizations, so the parent theme can be safely updated or replaced.
Conclusion
Deleting themes from WordPress is a straightforward task that gives you greater control over your site’s security, performance, and organization. With several methods available—from the dashboard to FTP and command line—there’s an approach for every skill level. By regularly tidying up your themes, you’ll keep your site efficient and better protected against potential risks.
Frequently Asked Questions (FAQs)
1. Can I delete my active WordPress theme?
No, you cannot delete the currently active theme. You must first activate a different theme before WordPress allows you to delete the one in use.
2. Will deleting a theme erase my site’s content or settings?
Deleting a theme only removes its design files and customizations within the theme folder. Your posts, pages, plugins, and general site settings remain safe and unchanged.
3. Do I need to keep default WordPress themes (like Twenty Twenty-One)?
It’s recommended to retain at least one default WordPress theme. If your active theme fails or is deactivated (due to an error or update), WordPress falls back to the default theme, providing a recovery option.
4. What should I do before deleting a theme?
Always ensure the theme is not active, back up your site, and save any custom code or files from the theme folder you may need later.
5. Can I reinstall a deleted theme later?
Yes. If you change your mind, you can always reinstall the deleted theme via the WordPress theme repository or by uploading the theme files again in the dashboard.
With this knowledge, you’re ready to confidently delete unwanted WordPress themes and maintain a secure, streamlined site. Your future self—and your website—will thank you!
