Style Manager --> Navigation and Breadcrumb Trail -> navbar
Find the following and comment out the following using <vb:comment> </vb:comment> (I would not remove this in case you get push back from members
Code:
<li class="navbithome"><a href="index.php{vb:raw session.sessionurl_q}" accesskey="1"><img src="{vb:stylevar imgdir_misc}/navbit-home.png" alt="{vb:rawphrase home}" /></a></li>
{vb:raw navbits.breadcrumb}
{vb:raw navbits.lastelement}
