Error when logging out

[FAST50]

When logging off my forum we see this message:
"An error occurred while attempting to log you out. Click here to log out."

When you click that link, the next message says something like: Logged out. All cookies cleared. ..and all is well.


I found this code at the beginning of my header.
Could this be the cause of my log out problem?

<script type="text/javascript">
<!--
function log_out()
{
ht = document.getElementsByTagName("html");
ht[0].style.filter = "progid:DXImageTransform.Microsoft.BasicImage(grays cale=1)";
if (confirm('$vbphrase[sure_you_want_to_log_out]'))
{
return true;
}
else
{
ht[0].style.filter = "";
return false;
}
}
//-->
</script>


Thanks for your help.

What version are you using? And did you revert the navbar when you last upgraded?

Version 3.5.3 and I have not upgraded yet. My forum is modified and the nav bar is located in the header.
