You should remove inactive themes
When creating a WordPress website, multiple themes are sometimes experimented with. No problem, of course, but once you have chosen a theme to continue with, it is good practice to remove the remaining inactive themes.
Why should I remove themes that are not active?!
The themes still exist on the server. Any data stored on the server can be used by a hacker or script to gain access to your website.
And there are several reasons to remove your inactive themes
- Themes you are not using take up space on the server
- Themes can serve as hiding places for backdoors created by viruses and hackers
- Themes need to be updated. They are recognized by WordPress, leading to update notifications every week/month, even though you are not using them!
I remove everything I don’t need, just like in my house.
Beware of your “child” theme!
Many frameworks have a child theme associated with them. Customizations are made within the child theme, and you wouldn’t want to lose those. Therefore, make sure your website is not using a child theme before removing any themes.
