Hi there. I was using a virtuemart theme module called Linelabox with your Bordeaux template and it works fine. Then I swapped to your Oxygen template and it has stopped working. I'm not getting any response from the module owner, so I thought I'd try here. With Oxygen it gives me a php error like this:
Warning: Invalid argument supplied for foreach() in /home/t/h/thestorygroup/public_html/testsite/modules/mod_linelabox/mod_linelabox.php on line 87

Possibly not a joomla51 issue, but very keen to get help from anywhere...
