Trying to get Paypal (Website Payments pro) Working, but no matter what I checkout I get the “Can’t process transaction: Merchant has configuration error msg...” I’m using a Paypal developers api test account with SANDBOX Flag ON. It keeps giving me the error.. i doublechecked the credentials as well. Could it be some thing else?
I also tried it with the live Paypal API and still the same error? Any ideas?
Again… This is pertaining to the PREVIOUS release (.12510) . I’d like to test on the newest one, but I can’t seem to get around the blank wizard error.
