Hi I am having the same issue as stated here: http://ellislab.com/forums/viewthread/91625/#463198
All of a sudden, my Admin page on one of my sites is no longer showing with the CSS and appearance it always has. It’s like someone trashed the CSS file or something—but I never touched anything.
So how do I go about getting my normal Admin style back? I’ve been using the default for years, and I have no clue as to what to do next…
Looks like there was a solution, but the link to the solution is not live anymore.
