I have a somewhat familiar problem. I have the Artificer theme and my "Shop" page is only displaying two columns. I had this problem a while back and fixed it by deleting a totally unrelated line of code in my custom.css file. Well, I no longer have that line of code in there, but I deleted all of the contents of the file to see if another line was causing the problem. The display still only showed two columns! I have restored the custom.css file, but since I now have no clue what to do, I'm hoping someone else has an idea. The URL is http://www.olbinternetservices.com/shop/shop/
Does anybody have any ideas?
