Forum:Infobox color problems

I have encountered some problems on the swtor wiki. As you can see here (look at the box below) and here, the background colors appear alternately in white.

I know, or think, it has something to do with the mediawiki:wikia.css and mediawiki:common.css pages but I can't find the problem.-- Darth Stefan Talk http://images3.wikia.nocookie.net/lostpedia/nl/images/e/e5/Stefan_handtekening.PNG  08:06, April 2, 2011 (UTC)
