WSOD on settings

Hi!
I downloaded and uncompressed corolla and adaptivetheme in /sites/all/themes.
Went ahead and activated Corolla, everything all right, but now can't open the theme settings. I get a blank white screen only.

Thing is, It worked all right but now won't. I tried removing adaptivetheme & corolla, redownloading etc but no luck.
Where do I start to track the problem? Why won't it show the settings? I can view and edit the settings of other themes, just Corolla's and Sky's I can't. The url is this site.com/admin/appearance/settings/corolla
Thanks a lot!

EDIT: FirebugforDrupal was the module causing the error.
