Hi, I've got a upgrade problem to. (Joomla 2.5.4 VM 2.0.2) Trying to upgrade to VM 2.0.6 doesn't work using the Joomla installer or the Virtuemart upgrade.
Also tried to use the Joomla tmp directory after reading http://forum.virtuemart.net/index.php?topic=101702.0
Tried changing the owner of all VM directories as well as setting the rights to various levels. Nothing seems to work.
When upgrading a tar file is put in the tmp directory (com_virtuemart.update.tar.gz)
When opening this file locally it is marked as corrupt and only contains the administrator files for com_virtuemart.
Mabye this helps somewhat for some searching for a solution.
I hope anybody can help.
