I have a custom theme that works fine. I want to use D7's 'Seven' theme for administration. However, despite it being chosen already, Drupal uses my custom theme for administration and editing.
If I change themes to a Drupal default theme like Bartik, then, I can change the administration theme to whatever I want, even my custom theme, and everything works as expected.
This tells me I have something wrong with my theme. What am I missing? Are there any default drupal theme variables that I need to include to make sure that the overlay theme is indeed Seven (or whatever I choose). What could be causing my theme to disregard my Administration Theme choice and use my custom theme regardless of the setting?
note: I am trying to give 'overlay' permissions to others and want them to use the Seven theme. I forgot to mention that this works fine if I am logged in as Admin (user 1) but everyone else gets the custom theme for admin regardless of what I choose.
