To load default jquery core file from CDN to WordPress, you need to simply copy and paste the following code in your theme’s functions.php file.
function replace_jquery() { if (!is_admin()) { wp_deregister_script('jquery'); wp_register_script('jquery', 'https://code.jquery.com/jquery-1.12.4.min.js', false, '1.12.4'); wp_enqueue_script('jquery'); } } add_action('init', 'replace_jquery');
