Fullwidth Easy Slider Not showing in IE or Edge

Fullwidth Easy Slider Not showing in IE or Edge.
Using WordPress version 4.5.2, Enfold Version 3.6.1

Website works perfectly in Chrome, Firefox, etc. But when viewed using Internet explorer or Edge the Fullwidth Easy Slider, Masonry Gallery and Animated numbers do not show – just leaves a blank space.

All plugins have been disabled. Made no difference.

Added :
function modify_jquery() {
if (!is_admin()) {
wp_deregister_script(‘jquery’);
wp_register_script(‘jquery’, ‘https://code.jquery.com/jquery-1.11.3.min.js’);
wp_enqueue_script(‘jquery’);
}
}
add_action(‘init’, ‘modify_jquery’);

…to the functions.php file and this got the Masonry Gallery images and Animated numbers showing – but still can’t get the Slider to work.
