I've tried everything, is not a alias, my Alert URL.
I created an example of subscription and pasted the code in a new html. Something arrives at the Alert URL, but none variable. I have checked the encrypted password over and over again, but nothing.
I downloaded the example, and in the first line I have checked all executable POST with a foreach, and recorded in the database. Then he put a exit.
But I do not receive any POST.
It is imperative to have verified my business account, to receive the $ _POST through the IPN, in test mode?
What am I doing wrong?
