I have set up PayPal V2.0 for my funnel but when I select PayPal to check out I get a message: “ Security header is not valid” and sometimes a red “Could not find payment information” appears inside of the order form.
Any ideas what could be causing this?
Additional PayPal V2.0 Questions:
What is supposed to be entered in the Gateway name?
Username and password are the PayPal account login I assume?
