Gator cache and WP-PostRatings

Hi, Have I code right? I have newest Gator cache and WP-PostRatings. Now on click on star not working script all right. Please help me to correct code.

    /**
     * Make WP-PostRatings compatible with the Gator Cache.
     */
    function wp_postratings_clear_gator_cache($rate_userid, $post_id) {
        if ($post_id && class_exists('WpGatorCache')) {
            //$options = WpGatorCache::getOptions();
            // NOTE: use standard WP function since the main class method getOptions() is protected
            $options = get_option(WpGatorCache::PREFIX . '_opts', array('refresh' => array('home' => true, 'archive' => true)));
            $path_ref = '';

            // purge cache of the rated post
            if (null !== ($path = parse_url(get_permalink($post_id), PHP_URL_PATH))) {
                WpGatorCache::purgePath($path);
            }
            // purge cache also for the page on which the post was rated (other than single)
            if (isset($_SERVER['HTTP_REFERER']) && '' !== ($path_ref = parse_url($_SERVER['HTTP_REFERER'], PHP_URL_PATH)) && $path !== $path_ref) {
                WpGatorCache::purgePath($path_ref);
            }
            // refresh home page if desired and not already cleared
            if ($options['refresh']['home'] && $path_ref !== '/') {
                WpGatorCache::purgePath('/');
            }
            // refresh taxonomy archive pages if desired and not already cleared
            if ($options['refresh']['archive'] && false !== ($terms = WpGatorCache::getArchiveTerms(get_post($post_id)))) {
                foreach ($terms as $term) {
                    if (null !== ($path_tax = parse_url(get_term_link($term, $term->taxonomy), PHP_URL_PATH)) && $path_tax !== $path_ref) {
                        WpGatorCache::purgePath($path_tax);
                    }
                }
            }
            // TODO: purge cache for other pages that might contain the rated post (e.g. post type archive)
        }
    }

//    add_action('rate_post', 'wp_postratings_clear_gator_cache', 10, 2);
