Project description
The function of adding goods to the basket from the catalog does not work. That is, one product can be added, and add another and go to payment is impossible. Error 500 and Not defined property "Bill.unset Attributes"
I didn't know where it was handled.
The person works on the link http://ogyrets.ru/op/catalog/category/id/11. Add the goods to the basket. Then you go into the catalog and add another product. After that, you can switch to payment.
I've got a mistake in this case.
I can choose one product in my script in the catalog and immediately switch to payment. If I add to the basket, then pressing the order button next to it, an error will occur.
I can just click Order now.
