Hi, I've checked in our template code there is original code for "customfields" .
Please rename folder "template/gk_storebox\html\com_virtuemart\productdetails" for a while and check if they appears or not in product view page? Than let me know...
I updated to the latest version but still no change.. Can you please give an answer that will cover my problem instead of dropping an answer like: "try to update to the latest version" I believe that in older days, 2 years ago you had a more responsible an reliable manner of dealing with bugs..
