Hi. we received an error in a customer shoppingcart . For other customersNopcommerce shoppingcart works well.
I think that this could happened due to discount settings: we create a new discount and then applied it on shoppingcart. The same discounts was after applied to other customer shoppingcart without problems.
I tried to solve it deleting the shoppingcart record for customer directly on database ... but error appear again when i choose a product and put in the cart. The product is added but when i click to shopping cart icons to view the product list Nopcommerce crash
