If you’re seeing this notice it means you have a version of the pro plugin installed that is out of date (before v2.13.0). Upgrading is important to receive bug fixes as well as new features as we add them.
If you would like to force hide this notification, you can do so by adding the following function to functions.php.
// Removes MetaSlider admin notice add_action('admin_head', 'ms_hide_admin_notice'); function ms_hide_admin_notice() { echo ''; }
