Error on site

[vodkaa]

Hi, while tryin to mark forum read ( http://carder.market/forumdisplay.php?do=markread ) i got an error, it must be about the security token, on navbar template fix this code and add the security token

<a href="{vb:raw $vboptions.vbforum_url}{vb:if "$vboptions['vbforum_url']", '/', ''}forumdisplay.php?{vb:raw session.sessionurl}do=markread&markreadhash={vb:raw bbuserinfo.securitytoken}">{vb:rawphrase mark_forums_read}</a>
