Hi. I had the same problem with module positions in my virtuemart shop and I couldn't figure out for the life of me why any modules wouldn't show up in the browse pages and the product details pages. The module would only show up iif I published the module to All pages but I didn't want the module on every page of my site. So I tried anything and everything to figure out what was going on and searched google for help when I found this post. I tried using the steps above but they did not work for me. I searched virtuemart forums for help but I still couldn't pinpoint the problem but I finally figured out what was wrong.

It was my own fault I guess.....

The quick answer is that in administrator backend I went to Menu > mainmenu created a new link to the Virtuemart component. After this new link was created in my mainmenu I checked to see what the Itemid was for this (virtuemart) component. For my site the Itemid is 213.

I also looked at all the other menus to find out if the itemid was the same in every one when I found the culprit. I had reinstalled the Virtuemart component so now it had a new itemid. The old itemid was 82. So I had a menu link in my othermenu with a different itemid that was causing conflict with the newly installed virtuemart itemid.

Hope I didn't confuse you here.

I deleted the link in my othermenu with itemid of 82 and made sure the module I wanted to show ONLY in my virtuemart store was published and set correctly.

And now the module I want to show only in the store works on every page of the store just the way I want it to.
