Some help please:
I have Joomla global user registration turned off, and VM silent registration turned on.
However I still get this message on OPC:
Error: Joomla Global User registration is turned off, but virtuemart is not configured to use NO REGISTRATION or SILENT REGISTRATION.
Solution: When Joomla registration is disabled you can use NO REGISTRATION or SILENT REGISTRATION with OPC.
When someone completes the checkout process they are not registered either.
