I just spent some time on the Virtuemart eCommerce bundle.
Do not use it!
The Virtuemart version is 1.1.2, not 1.1.3. Just install Joomla 1.5.9 as usual, and then install Virtuemart as usual.
What surprises me is that the JA-Larix theme looks incomplete. I don’t know how it is that there are no threads in the VM forum –nor my own forum — asking why the JA-Larix theme is producing errors. Well, it should because there are entire folders within it that are missing.
There is another problem. If you upgrade your “eCommerce” Virtuemart from 1.1.2 to 1.1.3, you then have to upgrade your JA-Larix theme as well (assuming you are using it). However, there is no JA-Larix theme for VM 1.1.3.
So you are faced with the decision to either upgrade JA-Larix theme files yourself, stay with VM 1.1.2, or change themes.
Remember that you have to upgrade your themes with each VM upgrade!
You are much better off not installing the VM eComm bundle.
UPDATE: The JA site’s JA-Larix is updated to VM 1.1.2 only.
