ribo Hi
If you click a product and it doesn't show the detailed page of that product, it means that it doesn't belong to any menu item yet and you should create a menu item type of Virtuemart for it.
ribo My only issue here is that I saw also that in quickstartpackage you have option shopingcart fo J4 in create menu item for virtuemart but i have only for J3
I'm afraid that I'm not entirely sure of this issue, could you clarify in more details?
