Hi,
This has been discussed many times in this forum. The problem is caused by missing "facebox.js" plugin. Because after VM2.0.22, loading facebox.js has become "optional".
Here is the solution.
Open this PHP file:
/templates/YOUR_TEMPLATE/html/com_virtuemart/cart/default.php
OR
/templates/YOUR_TEMPLATE/html/com_virtuemart/assets/include/flexibleMartGlobal.php
(either of these files would work, doesn't matter) Look at top of the file and find this line:
defined('_JEXEC') or die('Restricted access');
Right
after it, include these PHP lines:
JHTML::stylesheet("facebox.css","components/com_virtuemart/assets/css/");
JHTML::script("facebox.js", "components/com_virtuemart/assets/js/");
This patch will load the facebox.js in the shopping cart page and everything should work out just fine.
Regards
