 * Using plugin ver. 2.3.0, WP ver. 5.7
 * In admin sessions (all admin pages) I see the following warning:
 * `Warning: array_key_exists() expects parameter 2 to be array, bool given in /
   mysite/wp-content/plugins/wp-maintenance-mode/includes/classes/wp-maintenance-
   mode-admin.php on line 550`
 * Maintenance mode is not activated at this time. No errors are reported in the
   browser console.

 * Hello [@josiah-s-carberry](https://wordpress.org/support/users/josiah-s-carberry/),
 * I will investigate and add a patch in the next version. Until then, try to re-
   install the plugin (remove first, install after that).
