    Hi @acsafrica,

    I understand you’re experiencing frequent PHP deprecation errors on PHP 8.4 that are causing your website to become unresponsive. This specific error in the WooCommerce eval-math library is related to PHP 8.4’s stricter handling of null values.

    Here are some steps to help:

    • Make sure you’re running the latest version of WooCommerce, as newer versions often include PHP 8.4 compatibility fixes.
    • If these messages are causing your site to become unresponsive, you can temporarily suppress them by adjusting your wp-config.php file:
    error_reporting(E_ALL & ~E_DEPRECATED);

    This won’t fix the root cause, but it will prevent the warnings from flooding your logs and affecting performance.

    • If the it’s persistent and critical, consider downgrading PHP until WooCommerce releases a patch for full 8.4 compatibility.

    Let me know how it goes!
