Hi! I have a big problem with a Virtualmart Template created with the last version of TT7.
I installed a fresh new template in my working web site (no personalisations were made on the template) and it seemed to work well but my custom fields disappeared.
I tried to install a template made for Joomla and another one made for Virtuemart: the result does not change.
I didn't set the template as default in Joomla but I choose it in VirtueMart configuration for my shop.
Please note that custom fields work with a previous Joomla template ...
