How to display the cart module on my shop but not during the checkout ?
For that, you need to set the option "Force a menu on checkout" of the Checkout tab of the configuration to a menu where you don't want the cart (or create one specifically for that). Then, in the Joomla options of your cart module, that you can access via the Joomla module manager, unselect that menu in the "menu assignment" option and you won't have the cart module on your checkout.
Hope this will help you.
