Why should you remove a WordPress theme?

It is recommended that if you are not using a WordPress theme, you remove it from your website. Unused WordPress themes should be deleted for a variety of reasons.

Security Problems:

WordPress is a CMS (content management system) open-source platform that enables users to build and maintain websites by using the WordPress web browser interface. However, WordPress has a variety of security vulnerabilities. 

Hackers frequently exploit faulty theme code to inject malware, backdoors, and other nasty things into WordPress sites. The most common example of this is the use of a cross-site scripting (XSS) attack.

Storage Issue:

A theme is just a collection of files, so an unused theme is a bunch of unused files taking up space on your hosting server. 

We can easily see which themes are not active by looking at the list of installed themes. 

If you have an old theme on your site, there’s a good chance it’s not being used and can be deleted to save space. This can be quickly done by going to the WordPress admin screen and clicking.

Unusual Updates:

Even if you are not using those themes, you will continue to receive updates for them.

When should you delete unused themes?

You can delete most WordPress themes without harming your website. If you’ve decided to switch from one WordPress theme to another, you can delete the old theme without hurting your website. 

In this scenario, you’re deleting your old theme in order to make way for the new one. Likewise, if you’ve installed a new WordPress theme, you may want to delete the old one to avoid having two themes on your website at once.

When should you keep unused themes on your site?

While unused themes are usually a waste of space, there are specific situations in which you should maintain a deactivated theme. These are the following:

  • If you’ve ever changed your WordPress theme, you may have noticed that your old theme is still listed in your theme settings. 

Themes that are not active are not immediately deactivated by the WordPress system. Themes that are installed, but not active, are allowed to stay on your site. This is useful if you want to keep an old theme in case you need it later.

  • When it comes to the question about when you should keep unused WordPress themes, it seems that it depends on the type of website you have and what you want to achieve. 

If you want to keep a theme as a backup. For example, having a couple of the default WordPress themes on your site is relatively harmless.

Things to Do Before You Delete a WordPress Theme

You can build a complete WordPress backup if you have customized a WordPress theme and wish to keep those adjustments before uninstalling it.

As a backup, save the WordPress theme folder to your computer.

After you’ve made a safe backup of your old theme, you can delete it.
