Fatal error: Class 'ShopFunctions' not found

We haven't heard of this issue before. Can you provide some more details on your Joomla and Virtuemart versions? Once we know what environment you're working in, we can setup some tests to see why that call is failing.

Thanks,
Alex

It may be something that changed in the latest releases of Virtuemart. Our plugin was originally developed for VM 2.x, but it's been tested against the original 3.0 release. We haven't had as many users on Virtuemart lately, so it's possible a bug is present somewhere between our latest releases.

For now, I can only recommend disabling the Social Profile - Virtuemart 2 plugin. Once we investigate more and have an answer for you, we'll gladly let you know what we find.

Thanks,
Alex
