PHP Fatal error: Call to undefined function __wordpress_pf() in /home/httpd/vhosts/realfootbol.ru/httpdocs/wp-content/themes/ProSports/footer.php on line 6, referer: http://updownchecker.com/fe0b92ea-0c9c-e31...f4-00155d36955e

Вот сам подвал:
<div class="outer">
<div id="footer">Copyright &copy; realfootbol<a href="<?php bloginfo('home'); ?>"><strong><?php bloginfo('name'); ?></strong></a> - <?php bloginfo('description'); ?> - Powered by <strong>WordPress</strong>.</div>
<?php // This theme is released free for use under creative commons licence. //http://creativecommons.org/licenses/by/3.0/
// All links in the footer should remain intact.
// Warning! Your site may stop working if these links are edited or deleted ?>
<div id="info"><?php __wordpress_pf(); ?></div>
</div>
</div>
</div></div></div>
<?php
wp_footer();
echo get_theme_option("footer") . "\n";
?>
</body>
</html>

Обьясните не могу понять что такое?
