Hi,
I guess this is not used by most of us, but yet.....
All three buttons = Recommend to a friend + Print + PDF = are not working.
(Recommend to a friendgets the email along with an error: Notice: Undefined index: vendor in ...../components/com_virtuemart/controllers/productdetails.php on line 175).

Thanks - Drukman
