Pages bouncing between styles

[FockerFGAA]

So recently we had a style created specifically for our site. It is a very nice style imo. When you got to our forums (www.fvsports.com/forum/) the style shows up perfectly fine. However, when I log in it jumps to a style I used to use (a version of the default style). And again when I go into any of the actual forums it goes back to our style we currently use. Now it doesn't do it for a regular user that I created to test things with, so I am assuming that my admin powers somewhere is overriding it, but I don't see where that is an option. If anyone could point me in the right direction it would be much appreciated.
