Hi there.
I'm using ubercart and uc_protx to process my payments using SagePay (Protx). When the user is sent to the SagePay gateway, and they enter their details, the payment is accepted with no issues but are taken to the complete page on my drupal installation, which says the following: "Order complete An error has occurred during payment. Please contact us to ensure your order has submitted."
Sagepay will send a confirmation email but Drupal won't, because the order is never received.
Does anyone know why this is happening? Thanks in advance!
