vBSEO Tree in the AdminCP> vBSEO site map settings is a blank page

In my AdminCP at
vBSEO Tree then the sub link to vBSEO Sitemap settings is not showing me anything. It is just the blue background that is my adminCP color. vBulletin link is at the top.

What have I done?

Please try to modify includes/xml/cpnav_vbseo_sitemap.xml file:
FIND:

PHP Code:

  <navoption displayorder="20">
   <phrase>vbseo_sm_settings</phrase>
   <link>../{$vbulletin->config[Misc][admincpdir]}/options.php?do=options&amp;dogroup=vbseo_sitemap</link>
  </navoption> 


Replace with:

PHP Code:

  <navoption link="../{$vbulletin->config[Misc][admincpdir]}/options.php?do=options&amp;dogroup=vbseo_sitemap" displayorder="20">
   <phrase>vbseo_sm_settings</phrase>
  </navoption> 


Thanks Mert!!! What did I do to break this? Or how did this happen?

It was an error on our part, that file is out dated.
