Hello
VirtueMart 3.2.6
The constant VM_REV has not been set to the correct VM version.
(administrator/components/com_virtuemart/version.php)
In version >= 9194, the function vmJsApi::addJScript had one more parameter.
So 3rd parties developers adding a script via this function must check VM_REV.
and now the scripts are not loaded at all.
