Klasik Layout Problem

I just installed klasik under WPMU and when I go to the shop menu item, the catalog is layed out top to bottom, one item per row as opposed to four across. The url is https://dailysilverupdate.com/store/shop. I looked at the css and everything seems to be in order.

Thanks in advance for any help anyone can give me. I really like this theme and would love to get it working properly.
