AAC Paypal automatic payments doesn't load points on ZnoteAAC

Hi there! I wonder if someone can help me with this. I already tried the ZnoteAAC script that is used for automatic payments and it is sending me the USDs to my Paypal account, the thing is that the points aren't loaded in the server account. I saw many threads about this at OTland but couldn't find a proper solution to make it work.

For the moment all I know is that I must debug somehow in the znote_paypal table of phpMyAdmin when a transaction is done to know which error is triggered, but at the moment nothing happens/appears (I need to see if I can get a response check in the database). What I already did is:

  • Enable the Instant Payment Notification at Paypal
  • Update ipn.php to the latest one at ZnoteAAC github repository
  • Set up everything according to this video

Here's my config.php

and my getpoints.php (where the button to donate is loaded)
<?php require_once 'engine/init.php';
include 'layout/overall/header.php';

// Import from config:
$pagseguro = $config['pagseguro'];
$paypal = $config['paypal'];
$prices = $config['paypal_prices'];

if ($paypal['enabled']) {
<table border="0" cellspacing="1" cellpadding="4" width="100%">

I also added this after line 86 just after curl_close($cURL);
mysql_insert("INSERT INTO `znote_paypal` VALUES ('0', '0', 'response check: $Response', '0', '0', '0')");

But nothing happened.
Thanks in advance!

changed the config in paypal website too? to return your www.your_site/ipn.php?

the last time I had a problem with paypal it was because I hadn't set up my website correctly on their website.
I don't remember if it had something to do with HTTPS/HTTP

Thanks for the reply! Yes I have it
and even received an e-mail when the donation is made

Some stuff I did to bring some advances.

Changed ipn.php to a testing one provided here:

Here's the log result

And no points added (tested by re-sending the IPN to url)
I also attach the results of IPN history, where the transaction happens but the point doesn't get added
For further views I changed this setting at cloudflare

And changed this part of ipn.php

Some usefull links

Haven't tested the automatic payment yet, but wanted to leave this information here
