For a start, there are several javascript errors in the javascript console which you should look into - those aren't causing the infobox issue, but you should fix them all the same.

The normal Wikia/Oasis skin uses mediawiki:Wikia.css, and also mediawiki:Common.css on newer wikis, or if it's been requested for older wikis. Monobook uses Common.css only.

I thought this might be the problem, but I can't find the word "infobox" in either Wikia.css or Common.css

Where are you infobox styles kept?

edit: Monobook also loads MediaWiki:Monobook.css, which I didn't mention it because I didn't think that information would be useful, but as it turns out, you're already using, so I don't understand why that's not being loaded.

edit: So, there must be a problem in one of your CSS files.

edit: Found: MediaWiki:Common.css, broken since 2014-03-01 /* Allow for hiding text in compact form */ .compact-ambox .hide-when-compact { display: none;
