thanks for the resolution tip, i can't believe i didn't think of that. and what i meant to say happens when i load other themes, is that when i change to a theme other than 21, it doesn't load. it asks if i want to revert to default setting, and i click no, but it still stays at 21. the austerity is the only theme that loads now.

Plus, i checked my settings in the personal.rc and some other things, and they are as they should be, but still the !ThemePopup doesn't work.
