Hello,
I see what the problem is now, its in the header area for the category, where the print icon is. This and the DIV its in are pushing the content down.
What you can do is open up the "categoryChildlist.tpl.php" file located in:
components/com_virtuemart/themes/default/templates/common
Look for the
at about line 15 and put the below above it:
<div style="clear:both;height:10px;width:100%;"></div>
Let me know if this doesn't fix the problem.
Regards,
