Just recently had a website upgrade to a newer version of NopCommerce and we've had Atluz Nop Team, Pay using SagePay/Opayo plugin installed to take payment from our web sales.
we're having this reoccuring issue randomly where a customer will place an order, go through payment and then receive a order error message, but the payment has actually gone through.
the order sits in pending instead of the usual processing, which triggers a confirmation email to us and the customer.
Log level Error Short message Atluz Sage Pay found some error!
