In backend I just tried giving administrative rights to an "Administrator" level account, with such account I can enter Virtuemart where I checked I have "admin" rights however the system doesn't let me save the shopper group of any user. If I select a different shopper group and then save, nothing happens, the shopper group doesn't change, no error is triggered. Nothing changes.
Only accessing with the Super Administrator I am able to save shopper group as desired and the system correctly saves it.
WHY?
Joomla 2.5.3
Virtuemart 2.0.2 stable
Still no answer? Nobody?
It seems like you have several bug requests so maybe you're busy. I'll try to have a look about it by myself when I have some spare time and submit here the fix.
