 * Hi, we are currently running PHP v7.4 and your plugin is throwing this error.
   We are planning on moving up to V8.1.
 * PHP message: PHP Warning: Use of undefined constant php – assumed ‘php’
    (this
   will throw an Error in a future version of PHP) in /var/www/html/wp-content/plugins/
   popup-anything-on-click/includes/admin/metabox/report-metabox.php on line 74″
