Unable to check out...
Hello...
I have a site set up in sandbox mode with PayPal sandbox api authentication. When I enter my own valid Credit Card info (which I use regularly with success), I get the following error:
"Your transaction could not be completed. Either your credit card information or billing address has problems and cannot be processed"
How can I trouble-shoot this? I'm just getting to know PHP... my background is with C# and ASP.NET.
Thanks,
Andrew
