About: Jeremy Waite

I am having the same problem. I’m using PayPal Pro Forms with custom=”www.[mydomain].com” in the form schortcode. I am getting the Unable to verify $_SERVER[“HTTP_HOST”] error in my IPN log when issuing a refund through PayPal and it will not downgrade the user even though I have set all the settings to do so. I have also checked that the PayPal IPN address is

http://www.[mydomain].com/?s2member_paypal_notify=1

(with the www). We can manually downgrade users, but I would still like a resolution.

Here is my IPN log:
