Hello,
I am unable to take payments using SagePay due to the following error:
Payment has failed, please reload checkout page and try again. Your card has not been charged.
I tried to upgrade the extension via Magento Connect and it updated fine but did not correct the issue. However after upgrade I am unable to access the SagePay config page in backend now, it just appears completely white. I have refreshed cache and logged out and back in but that did not resolve it.
The main priority is to get the payments working. Any help would be greatful Thank You.
