I've integrated VevoCart into our site, using Linkpoint as the processor. All seemed to be working well. In demo mode, everything was processing fine.
I switched to live mode and got an error but figured out that it was because the demo Store number and .pem file were in place.
I changed to the live numbers, and now when I process a card, I get a blank error message with no description. It just says:
"Error Message:
Re-enter payment details."
Any ideas?
