How to offload CSS and JS files from wp-content/themes folder?

Are you using a child theme? Is get_template_directory_uri() function returning the correct URL? My suggestion is to use get_stylesheet_directory_uri() instead. wp_enqueue_style( ‘validationEngine.jquery’, get_stylesheet_directory_uri() . ‘/assets/css/validationEngine.jquery.css’, array(), false, ‘screen’ ); wp_enqueue_style( ‘main’, get_stylesheet_directory_uri() . ‘/assets/css/main.css’, array(), false, ‘screen’ );
