Issues with file /includes/autoload_func.php

ZC v.2.0.1

Since having PayPal RESTful installed and set up I seem to be generating multiple bugs on a daily basis and they all are of the same format below:
[26-Sep-2025 05:03:03 UTC] PHP Fatal error: Uncaught Error: Class "notifier" not found in /includes/autoload_func.php:47

I am not tech savvy and have no idea how to fix the above. Can anyone suggest an easy fix that even I can implement?
Thanks in advance, John.

A minor edit to the /includes/auto_loaders/webhook.core.php file.

Find this section at the top of the file

//- notifier class loaded via psr4Autoload.php
$autoLoadConfig[0][] = [
    'autoType' => 'classInstantiate',
    'className' => 'notifier',
    'objectName' => 'zco_notifier',
];

... and add the highlighted section, noting that this change is applicable for all supported Zen Cart versions (i.e. zc158 through zc210):

//- notifier class loaded via psr4Autoload.php; reloading
//- here for older versions of Zen Cart that don't load the
//- class via an autoloader.
$autoLoadConfig[0][] = [
    'autoType' => 'class',
    'loadFile' => 'class.notifier.php',
];
$autoLoadConfig[0][] = [
    'autoType' => 'classInstantiate',
    'className' => 'notifier',
    'objectName' => 'zco_notifier',
];

Sigh, once the above change is added you'll run into another. Here's another addition that will correct that

//- notifier class loaded via psr4Autoload.php; reloading
//- here for older versions of Zen Cart that don't load the
//- class via an autoloader.
$autoLoadConfig[0][] = [
    'autoType' => 'class',
    'loadFile' => 'class.notifier.php',
];
$autoLoadConfig[0][] = [
    'autoType' => 'classInstantiate',
    'className' => 'notifier',
    'objectName' => 'zco_notifier',
];
$autoLoadConfig[0][] = [
    'autoType' => 'class',
    'loadFile' => 'class.phpmailer.php',
];
/**

 *
 * $zcDate = new zcDate(); ... will be re-initialized when/if the require_languages.php module is run.
 *
 */
//- zcDate class loaded via psr4Autoload.php; reloading
//- here for older versions of Zen Cart that don't load the
//- class via an autoloader.
$autoLoadConfig[5][] = [
    'autoType' => 'class',
    'loadFile' => 'zcDate.php',
];
$autoLoadConfig[5][] = [
    'autoType' => 'classInstantiate',
    'className' => 'zcDate',
    'objectName' => 'zcDate',
];

Actually ... just replace the /includes/auto_loaders/webhook.core.php file with the following:

That'll be part of the upcoming v1.2.2 release of the payment module.

Thank you for the responses. I will copy and paste your final solution into a txt file and hold it in reserve. I am hoping that the guys at Jeandret may have fixed the problem. I am waiting to see if any further debug logs are created. If they continue I will implement the change.
Again, thank you for your help in this matter.
Best regards, John.

No problem; thanks for your posting! That's what will get the issue corrected for everyone.
