Forgive me if this has been addressed before but I've not been able to find a solution. I'm using zencart 1.5.1 and Stock by Attribute 1.5.1.2.

The problem is with admin access management. Super users can use the module with no problem and it works great, other users, with the module allowed in their admin profile can access it but when the try to save get a restricted access message.

Looking at the admin logs it appears that page which "normal" users have the problem accessing is products_with_attribute_stock_ajax.php but I've no idea how to correct this.

Any help would be very welcome.
