 * Hello, thanks for the plugin. Could you please make it work with PHP8+ without
   warnings? One of my email accounts gets messed up with PHP warnings from cron.
 * `PHP Warning: Undefined array key "REQUEST_METHOD" in .../plugins/clear-autoptimize-
   cache-automatically/clear-autoptimize-cache-automatically.php on line 99`
 * It would probably be enough to change line 99 of the php file from
 * `if ( $_SERVER['REQUEST_METHOD'] === 'POST' ) {`
 * to
 * `if ( isset($_SERVER['REQUEST_METHOD']) && $_SERVER['REQUEST_METHOD'] === 'POST'){`
 * thanks, Andreas
