Hi there, I upgraded the prestashop install of one of my friends and now when we add a product to the cart, no matter which size you pick, the one saved in the cart, is the default one. It is then impossible to order the size you want. You can see the problem here by adding a ring to the cart with a size (taille) != 48 http://padam-padam.com/eshop/index.php?id_category=3&controller=category I can't see why it doesn't work. Thank you for your help! Alexis
