[Hennie]

Hello,
just upgraded to VM 2.0.20b (from 2.0.20a). When, in the shop, I click on the product for product detail, the product is disapeared and the category layout is showing again.

I'm using Joomla 2.5.9
kind regards,
Hennie

Did some major testing... it seems that al connection with the product detail page is gone..
Anyone experiences the same problem?
