First of all, I have no idea what's causing this problem, so apologies if this is in the wrong section.
A couple years ago on one of my wikis, I made some sort of change to the content page width in order to make it wider. This was way back in 2011, and Wikia has since made that change unnecessary. For the life of me, though, I haven't been able to figure out exactly what I changed. Now all of a sudden the text on content pages has been shoved to the left. Here's a screenshot so you can see what I mean.
Since this only happened recently, I suspect it might have something to do with the Darwin layout, but I'm not sure. Without knowing exactly what I changed years ago, I can't be certain. I've tried changing Wikia.css for both MediaWiki and my own personal preferences, but apparently they have nothing to do with it. Is anyone able to help?
