I have inserted all the API details into my shoppingcart( aspdotnetstorefront 8.0.1x and everyting seems to be correct. When i try to checkout at my site by clicking the paypal express checkout button, it takes me to paypals site and I manage to log in as a buyer to my paypal account to pay for product. then it takes me to my own site to select shipping and i select it. last step is to place the order and when I click the place order on my site it gives me a error like this:"Please select a valid payment method to continue checkout". And the only option is Credit Card. Why is it doing this?
Can you please help in this issue
