We have been facing this issue for over 1 months now… I reported it in this case “Follow up on issues with orders out of stock still available for purchase” but it doesn’t fix it… Cscart needs to do something about this as soon as possible. For example, 2 items in prodcut stock on the system and buyer could order 4, then the product goes to -2 in stock. If paid through stripe, the order gets paid and changes to open and the buyer is already charged then thinks that order is paid and should be processed. Now vendors have to deal with the chargebacks on refund and also disappointing the customers and also having to explain all the time that the system has error and so on… This is becoming unbearable.!!
