Hi,
Thank you for the answer.
The problem was that JQuery 3 was not able to work with metaslider.
My old code was:
wp_deregister_script(‘jquery’);
wp_register_script(‘jquery-3’, get_template_directory_uri() . ‘/js/jquery-3.1.1.min.js’ , array(), ‘v3.1.1’, false);
wp_enqueue_script(‘jquery-3’);
Now I use jquery + jquery 3 and that’s working!
