I did a template change in my mail_html_header.php as told here:
http://forum.virtuemart.net/index.php?topic=109226.msg365917#msg365917 (http://forum.virtuemart.net/index.php?topic=109226.msg365917#msg365917)
Now with the latste VM 2.0.20b it is giving me the following error
Undefined variable: virtuemart_vendor_id
I can't find any thing in the change logs that are over here:
http://forum.virtuemart.net/index.php?topic=113052.0 (http://forum.virtuemart.net/index.php?topic=113052.0)
That this variable has been changed?
