Question
Why is the get-magic-quotes-gpc function not working in PHP 7.4?
Answer
PHP has removed this function in version 7.4, which you can find here:
https://www.php.net/manual/en/function.get-magic-quotes-gpc.php
so this is not a limitation of EasyApache and cPanel & WHM, but a change from PHP itself. If you have tools using this it would be best to use an older PHP version, such as 7.3, while you work to get your software updated.
