The cart module has a quick cart feature in Joomla 1.5. After migrating my site to Joomla 2.5 I installed DMS and enabled the cart to find out there is no quick cart anymore. Please tell me it´s a bug and not a feature as I choosed my template for the usage with the quick cart.
I sent you the updated module via support ticket. If anyone has same issue, you can download the updated package from My Downloads section or get the updated module here, re-install it to your site and you will see a setting which allow you to use Quick Cart .
