firstrebel,
You need to remove all of the code from the opening if to its closing if. There is another if statement nested inside of this one that you will also be removing as tony mentioned.
You need to remove all of this code:
Code:
<if condition="$show['guest']">
<!-- guest welcome message -->
<tr>
<td class="tcat" colspan="<if condition="$vboptions['showmoderatorcolumn']">6<else />5</if>"><phrase 1="$vboptions[bbtitle]">$vbphrase[welcome_to_the_x]</phrase></td>
</tr>
<tr>
<td class="alt1" colspan="<if condition="$vboptions['showmoderatorcolumn']">6<else />5</if>">
<phrase 1="faq.php$session[sessionurl_q]" 2="register.php$session[sessionurl_q]">$vbphrase[first_visit_message]</phrase>
</td>
</tr>
<!-- / guest welcome message -->
</if>
