If you migrate an existing WordPress site to Shifter from another hosting provider that site may include something called MU-Plugins.
MU-Plugins are "Must Use" Plugins. They are called that because they are always on, they cannot be deactivated or deleted from the WordPress Dashboard. Most of these plugins do a lot of helpful things and it's common for a hosting provider to offer them.
At Shifter, we install a few automatically on each site. They include a helper plugin for our static site generator, another helper plugin that works with Redis cache and more. In short, they are necessary while using this platform.
If there's a plugin from a previous hosting provider or a MU-Plugin that's giving you trouble this is one way to remove it.
- Be careful when modifying your site manually. There is not undo action when removing entire folders so be careful.
- Shifter manages the WordPress side of things. If you made an error within WordPress itself, just start and stop your WordPress container or reach out for help.
- Don't remove Shifter related MU Plugins. Most of them are necessary some of them are helpers. If you have a question about any, please ask us! 👍🏼
How to remove MU Plugins
1. Install File Manager
Start by installing the File Manager WordPress plugin. There are a few in the plugin directory and for this example I've installed the top result.
2. Navigate to wp-content
After installing and activating File Manager you can navigate to the WordPress Content (wp-content) folder. There you'll find folders such as plugins, mu-plugins, themes, uploads, and more.
Open up the
./mu-plugins/ folder and locate the Must Use plugin you want to remove. Right click on that plugin's folder and delete it.
