Admin Forum:Logo backgrounds not working anymore...

My upper banners are all gone:

I already checked in the CSS validator, no errors at all. Does this have to do with a recent wikia change? They were all working a few days ago, and my absent mindedness is to blame for not noticing exactly when they went poof! I do have a hint from this from December 3rd, it is gone in the screenshot, so I am guessing that's when I lost them? Any help is appreciated! --Liliana (my talk). 03:53, December 15, 2012 (UTC)
