stripslashes became deprecated in php 8.1 so its use is causing the issue.

You make use of a plugin called 'Simple Popup' which has not been updated since zen cart 1.3.9. I haven't checked it but my guess is this plugin is the culprit.

BTW I should have mentioned I know your on php 8.1 as you mentioned it in another thread.
Going to an earlier version of php might make this go away, however this is obviously not recommended - either find a way to upgrade - or see if there's another plugin that meets your needs.

FWIW, I'm not seeing such a deprecation notice on stripslashes in the PHP documentation: https://www.php.net/manual/en/function.stripslashes.php

What I am seeing is a change to /includes/modules/pages/popup_image_additional/header_php.php:

  $_GET['products_image_large_additional'] = str_replace(' ', '+', stripslashes($_REQUEST['products_image_large_additional'] ?? ''));

Thank you Lat9

I have made the change and will see how it goes.

You assistance is greatly appreciated.
