How to create a theme which only administrators can use?

Hello

You can use Safe Mode (just like your moderators) to disable themes.

With custom sections you can make your quick route to /safe-mode

1. Create a custom section to your sidebar like this.
   

   
   
   This should looks like this. (Add a title, Name and Link /safe-mode) Be sure you don’t check the Make this section public and visible to everyone checkbox.
   
   

2. It will place in the Navigation Menu (sidebar) custom section.
   

   

3. Here you can disable the themes and theme components. Click Enter Safe Mode button.
