Hi there,
Try adding the following code in the functions.php of your active theme:
if (defined('YITH_WCWL')) {
if (!function_exists('yith_wcwl_enqueue_back_required_assets')) {
function yith_wcwl_enqueue_back_required_assets()
{
$suffix = defined('SCRIPT_DEBUG') && SCRIPT_DEBUG ? '' : '.min';
$version = defined('WC_VERSION') ? WC_VERSION : '';
wp_enqueue_style('woocommerce_prettyPhoto_css', plugins_url('assets/css/prettyPhoto.css', WC_PLUGIN_FILE), array(), $version);
wp_enqueue_script('prettyPhoto', plugins_url('assets/js/prettyPhoto/jquery.prettyPhoto' . $suffix . '.js', WC_PLUGIN_FILE), array('jquery'), '3.1.6');
wp_enqueue_script('prettyPhoto-init', plugins_url('assets/js/prettyPhoto/jquery.prettyPhoto.init' . $suffix . '.js', WC_PLUGIN_FILE), array('jquery'), $version);
wp_enqueue_style('yith-wcwl-main', YITH_WCWL_URL . 'assets/css/style.css', array('jquery-selectBox'));
}
add_action( 'wp_enqueue_scripts', 'yith_wcwl_enqueue_back_required_assets', 9999 );
}
if (!function_exists('ywfav_add_fontawesome')) {
function ywfav_add_fontawesome()
{
wp_enqueue_style('fontawsome', 'https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css');
}
add_action( 'wp_enqueue_scripts', 'ywfav_add_fontawesome', 99 );
}
}
If still not work, I recommend you to contact your theme support in order to see how add the shortcode in the theme template.
Let us know any news.
Best regards.
