• Are you using a specifing theme? The injection of jQuery is usually located in the functions.php file of your theme - using the function add_action('wp_enqueue_scripts', 'XXX_scripts'); – F3L1X79 Commented Jul 2, 2019 at 7:54

• You can place you jquery above slider's jquery, but it will be most probably overwritten. You can replace slider's version of jquery with the desired one, but that might lead to another pack of problems. – Alex Stulov Commented Jul 2, 2019 at 9:10

Solution may be found here: https://stackoverflow./a/23551006/3933603 , from @deweydb.

Add these lines inside your theme folder's function.php file:

//remove the default jQuery script
add_filter( 'wp_default_scripts', 'change_default_jquery' );

function change_default_jquery( &$scripts){
    if(!is_admin()){
        $scripts->remove('jquery');
    }
}

//inject a new one from a remote source
add_action('wp_enqueue_scripts', 'ocean_theme_scripts');

function ocean_theme_scripts() {
    if(!is_admin()){
        wp_register_script('jquery221', '//code.jquery./jquery-2.2.1.min.js', null, null, true);
        wp_enqueue_script('jquery221');
    }
}

If you are using any caching plugin like wp fastest cache, autoptimize etc. then please remove it and check if it is working or not because this error is raised due to some jquery conflict. if it is working after disabling plugin it means there is problem in caching plugin.
