Has anyone got this to work?

I have been trying for days.

I am on public IP, no firewall and the URL is configure for paypal as follow:

notify_url=http://X.X.X.X/A2Billing_UI/paypal/ipn_res.php

Paypal takes payment, A2billing doesn't get update.

Here is the error log

[Sat Nov 11 23:01:09 EST 2006] paypay_ipn notification

If your php installation is new eg. php5 or even php4 then

Line ~35 of - /var/www/html/A2Billing_UI/paypal/ipn_res.php

change : $paypal_info = $HTTP_POST_VARS;
to: $paypal_info = $_POST;
