Hi,
jParameter has been deprecated in J3.3, You can't fix this problem by patching, instead the jParameter should be replace with new Joomla API
PureMart is not compatible with Joomla3.3 + VM3.0
You should be using Joomla2.5.x + VM2.5.x to use the PureMart (for now).
See this link:
www.flexiblewebdesign.com/Virtuemart-Templates/PureMart
it says: SOON: Virtuemart 3.x + Joomla 3.x support is coming soon!
topic is closed.
Regards.
