    Hello,

    On WordPress 5.9.3 and PHP 8.1 I have the warnings :
    PHP Warning: Undefined variable $class_name in …/wp-content/plugins/all-404-redirect-to-homepage/functions.php on line 28
    PHP Warning: Undefined variable $class_name in …/wp-content/plugins/all-404-redirect-to-homepage/functions.php on line 40

    For information, no warning with PHP 7.4 or PHP 8.0.
