 * Hi. Your plugin is nice. But sometimes result in a database error in my apache
   error.log. One example is shown below:
 * WordPress Database Error Column ‘type2’ cannot be null for query REPLACE INTO`
   dbprefix_wpss_links` (`url`, `type`, `type2`, `id`) VALUES (‘/2008/04/560/article-
   slug-example/feed/’, ‘singular’, NULL, NULL) made by require(‘wp-blog-header.
   php’), require_once(‘wp-includes/template-loader.php’), do_action(‘template_redirect’),
   call_user_func_array, wpss_footer

 * I cannot reproduce this error.
 * What is 2008/04/560/article-slug-example?
    Post? Custom post type?
