Hi Tom, great script! I'm trying to apply your code into my website. When I try to use the simulator it says: IPN Result:
ERROR:
http response error: HTTP/1.1 401 Authorization Required

I'm using this free hosting to test my web: https://pcontrol.cdmon.com/. Also I have had the "IPN handler did not return array" error but I commented the code that you said. Any idea??

>http response error: HTTP/1.1 401 Authorization Required

That's very strange. The error message is a general error message you see on Internet when you try to access the url that requires authorization. So, it's not specific to the script. You need to change some conditions and see if it makes any differences like install it in another location on the same web site.
