Problems with Youjoomla-templates and categories view in Virtuemart

I know this problem has been addressed before, but I haven't seen any solutions. When using Youjoomla-templates (regardless which I think) together with Virtuemart, the Youjoomla-templates will not show categories in a row. Instead the thumbs ore icons for the categories are shown in one single column.

Look at the link. If I switch to any other template than Youjoomla the two thumbs "kategori 1" and "kategori 2" will show beside each other, as they should.
***
Inside each category there are no problems showing the products in a row.
***
I presume the problems with the categories view happens because of a missing "end"-tag in a css- or php-file in the Youjoomla-templates, but I have no idea were.
***
I'm not absolutely sure, but I think this have been a problem since Joomla 1.5
