Hi, since you provide the template without the latest version of k2 store I would like to help me to modify the default.php of the template override of the mod_k2store_cart. Notice that I have already updated to the last version of K2Store (3.8.3).

The problem is that css are being losted and I receive the following ' {"response": {" ' in the top-right position of the cart as you can see from here http://olneva.com/shop/shop-1/item/38-wooden-evening-bag

Thank you in advance.
