'Save' and 'Save and Close' product edit not working

[xur82]

Joomla 3.4.1
VM 3.0.6.3

I recently updated VM and Joomla and I've lost the ability to save products. I have been through the posts and tried all manor of things..

I have also been going through my plug-ins turning them off and that didn't help.

I have another site running J 3.4.0 and VM 3.0.6.2 and I have the two site windows open next to each other. I have been checking the settings are all the same.

Has anyone had any problems with upgrade? Or is it something I've done and missed maybe, just wanted to check.. I've spent many hours now trying to put this right to no avail.

Thanks

It is a problem with using J3.4.1 and is known.  http://forum.virtuemart.net/index.php?topic=128952.msg443518#msg443518
