please instruct me how to allow regular users (non-admins) to use Seven theme to edit content. Now users are forced to edit content using the default drupal theme which wasn't designed for this purpose (looks ugly). Is it matter of some permission? Admins are editing with Seven theme without problem.
I've found some topics about more complex cases with module recommendations like this: http://drupal.org/project/themekey . As my case is pretty simple, I decided to ask!
