Hi, I'm just setting up a custom shopping cart for my website. I'm using the standard HTML form code which is submitted to https://www.paypal.com/cgi-bin/webscr In sandbox mode, its all working well. When going live, I've changed the paypal email address & url to the above. When making the purchase, the buyer is taken to paypal. After authentication, I see a page with a bug button which says "Return to Merchant" and nothing else. There is no other message or error. What is the issue and how do I fix this? Thanks for the help!
