When setting up a PayPal payment gateway, I received the following usage note:
"Usage Notes: You should enable IPN in your PayPal account and leave the URL blank"
When I try to do that, I get the following PayPal error message:
"You must enter a properly formatted URL into the Notification URL field in order to activate Instant Payment Notification."
Has anyone else experienced this problem and, if so, what is the solution?
