This is what i found when i searched for "&u=$bbuserinfo[userid]" this line is from my "username_loggedin" template.
I couldnt find "$vboptions[bburl]/login.php?$session[sessionurl]do=logout" any where else but in my "username_loggedin" template.
(This is what is in my "username_loggedin" template")
Code:
<tr>
<td class="alt1"><b>$vbphrase[logged_in_user]:</b></td>
<td class="alt1">$bbuserinfo[username] <span class="smallfont"><a href="login.php?$session[sessionurl]do=logout&u=$bbuserinfo[userid]">$vbphrase[log_out]</a></span></td>
</tr>
