Hi,
PureMart is compatible with "all" joomla templates if the Joomla Template is plain.
What i meant by "plain" is; Joomla Template shouldn't be touching anything in the Virtuemart pages, technically it shouldn't be "Virtuemart-Ready".
Because you are going to make your plain joomla template as Virtuemart-Ready joomla template by installing PureMart or CleanMart.
(PureMart and CleanMart would still work with Virtuemart-ready joomla template, but there will be some CSS overriding, those CSS overridings should be eliminated.)
Regards.
