For those having trouble, please check this plugin...

Advanced Application Form - parse_templates hook

And make sure that this is what is in the code..

if ($vbulletin->options['advapp_enable'])
{
	$notlogged = $vbulletin->userinfo['userid'];
	if($notlogged == 0)
	{
		$usergrp = 1;

	}
	if (!is_member_of($vbulletin->userinfo, explode(',', $vbulletin->options['advapp_perms'])) && !in_array($usergrp,explode(',', $vbulletin->options['advapp_perms'])))
	{
		$applications = $vbulletin->db->query_read("SELECT * FROM " . TABLE_PREFIX . "advapp_applications ORDER BY type ASC");
		while($application = $vbulletin->db->fetch_array($applications))
		{
			if ($vbulletin->options['advapp_inmenu'] && $vbulletin->userinfo['posts'] >= intval($application['postcount']) && is_member_of($vbulletin->userinfo, explode(',', $application['usergroup'])) && $application['community'] && $application['active'])
			{
				$template_hook['navbar_community_menu_end'] .= '<li><a href="application-forms.php?appid=' . $application['appid'] . '" title="' . $application['description'] . '">' . $application['type'] . '</a></li>';
			}

			if($vbulletin->options['advapp_navtabs'] && $application['navtabs'] && $vbulletin->userinfo['posts'] >= intval($application['postcount']) && is_member_of($vbulletin->userinfo, explode(',', $application['usergroup'])) &&  $application['active'])
			{
				$pop_options .= '<li><a style="color:' . vB_Template_Runtime::fetchStyleVar('navbar_selected_popup_body_a_Color') .'"  href="application-forms.php?appid=' . $application['appid'] . '" title="' . $application['description'] . '">' . $application['type'] . '</a></li>';
			}
		}
		$vbulletin->db->free_result($applications);
	}

	if($vbulletin->options['advapp_navtabs'])
	{
		$templater_nav = vB_Template::create( 'advapp_poptab' );
		$templater_nav->register('title', $vbphrase['advapp_title']);
		$templater_nav->register('options', $pop_options);
		$template_hook['navtab_end'] = $templater_nav->render();
	}

$vbphrase['powered_by_vbulletin'] .= '<div>Advanced Application Forms 1.0.9 ? 2011 by Snog</div>';
}

It seems somehow the last part of the plugin might not be being imported properly on some systems.
