Hi I am having a similar problem. I am testing my page and have set it up with paypal website payment standard sandbox. When I check out and get sent through to Paypal I get the following message:
Is this something to do with my settings? I have shipping address requirements set to 2 and address override set to 1.Unable to process payment. Please contact the merchant as the shipping address provided by the merchant is invalid, and the merchant has requested that your order must be shipped to that address.
Any help would be appreciated.
Andy
