I am running Joomla 1.5.26 and Virtuemart 1.1.9 currently and am about to upgrade to the latest releases this month but wanted to test this module first.
This has been tested in IE and Safari and neither show the tabs.
The code has been placed within the Virtuemart Product Description, below the product description. The frontend only shows the product description followed by the code in your example and doesn't generate the tabbed format?
Any ideas? I have searched the forum but didn't come across a solution?
