Your Virtuemart installation contains an error: No user is marked as vendor. Please fix this in your phpMyAdmin and set #__virtuemart_vmusers.user_is_vendor = 1 and #__virtuemart_vmusers.virtuemart_vendor_id = 1 to one of your administrator users.
Can you made 1 button to fix it in new version of VM? im understand how to fix it.

"Just go to the "Tools Migration" thing and set there the desired id of the vendor."
