I am trying to create an online store whose deliveries will be handled my company. I installed the Paypal USA module to handle payments and created virtual products so that shipping would not be an issue. Using paypal sandbox I successfully made a test purchase (received invoice, email and all).
Today when I tried to make the same purchase, I get the "We're sorry, PayPal doesn't allow residents of United States to ship purchases to [country]." error at Paypal.
What could be the issue?
