 * Great plugin! Just have a small issue.
 * Seeing this on PHP 8 when visiting the settings page:
 * `PHP Warning: Undefined array key "mouse_hover_only" in /wp-content/plugins/flying-
   pages/settings/settings.php on line 16PHP message: PHP Warning: Undefined array
   key "disable_on_login" in /wp-content/plugins/flying-pages/settings/settings.
   php on line 20" while reading response header from upstream, request: "POST /
   wp-admin/options-general.php?page=flying-pages HTTP/2.0", upstream: "fastcgi://
   unix:/run/php/php8.0-fpm.sock:"`
