My site is processing credit card orders successfully, but when the order completes, the invoice gets generated as normal, but no products are added to the invoice (the amounts show up, but dont reflect any discounts, and the Items Invoiced section is blank). PayPal checkout results in an error about the totals not matching “The totals of the cart item amounts do not match order amounts”. This is causing a myriad of other little issues, like discounts not being applied correctly (the full amount of the order before discount gets charged) and orders not being marked as complete when it is marked as shipped. Any idea what can cause this group of issues?
