2 Questions here. I am trying to test the standard paypal. I have my sandbox credentials in appconfig. I tested the sandbox on another site (not using ASPDNT)it works great there. I am getting this error on the paypal sandbox site
We cannot process this transaction because there is a problem with the PayPal email address supplied by the seller. Please contact the seller to resolve the problem.
Is this a problem with the customer email or my business email?
AND......... I have been unable to use paypal expres at all. Do I have to have PayPal Website Payments Pro (enables PayPal Express Checkout also) US Only CHECKED? iF YES how do I use AUTHORIZE.ET
