Issue with Orders not changing status to Processed from Pending but payment being taken

Hello,

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.

any advice on how to resolve this?

Thanks

J

Any errors in the log ?
Did you contact the developer - I assume Atluz Nop Team - to get them to check the operation

Hello,

I believe installing the latest version of the .NET 7 runtime will resolve your issue.
