Hi laz18345,
You can add the following snippet of code into wp-content/themes/s5theme/vertex/cmscorefunctions.php file (under line: 54)
if (!is_admin()) add_action("wp_enqueue_scripts", "my_jquery_enqueue", 11);
function my_jquery_enqueue() {
wp_deregister_script('jquery');
wp_register_script('jquery', get_template_directory_uri()."/js/jquery/jquery.min.js", false, null);
wp_enqueue_script('jquery');
}
