 * Hi,
 * is there a way to trigger the 404 error, so the is_404() will return true?

 * Hello,
 * Can’t this just be triggered by visiting a random URL on your website which doesn’t
   exist?

 * No, I don’t want to trigger it myself, I want to trigger it from the theme or
   plugin files. wp_redirect() to inexisting random URL is also not an option.
 * EDIT:
    ok, I found it in the source code.
 * eg.:
    global $wp_query; $wp_query->set_404();
