I have setup a sandbox Website Payments Pro Hosted Solution in my website. I'm using one page checkout. When I select my payment method to Payment by cards or by PayPal account a message shows below the radio button saying You will be required to enter your payment details after you place an order. But after I place the order shows a PayPal error This transaction can't be processed. Please pay with another card and do not show a place to enter payment details such as credit card details.
