Ever since upgrading one of my clients Opencart installations from 1.4.7 to 1.4.9.1, they have not been able to receive a payment via PayPal. Customers receive the quoted message. Originally, there was no PDT token added. Thinking that it could be this, I then created a PDT token, added it to the settings in Opencart. Same error.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. If this payment is for an eBay listing, you can contact the seller via the "Ask Seller a Question" link on the listing page. When you have the correct email address, payment can be made at http://www.paypal.com.
The email address being used is their valid PayPal email address. I even tried my own PayPal account for testing purposes and the same error.
Am I missing something here???
