Sorry, I don't seem to have permission to post code, but if you look at this area of your template:
<if condition="$show['avatar']">
<div class="smallfont">
<br /><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$post[avatarurl]" $post[avwidth] $post[avheight] class="avatar-custom" alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a>
<div class="smallfont">
<br />
<if condition="$post['joindate']"><div>$vbphrase[join_date]: $post[joindate]</div></if>
<if condition="$post['field2']"><div>$vbphrase[location_perm]: $post[field2]</div></if>
<if condition="$post['age']"><div>$vbphrase[age]: $post[age]</div></if>
<div>
$vbphrase[posts]: $post[posts]
</div>
$template_hook[postbit_userinfo_right_after_posts]
<if condition="$show['infraction']"><div>$vbphrase[infractions]: $post[warnings]/$post[infractions] ($post[ipoints])</div></if>
<if condition="$show['reputation']"><if condition="$show['reppower']">$vbphrase[reppower]: <span id="reppower_$post[postid]_$post[userid]">$post[reppower]</span> </if><div><span id="repdisplay_$post[postid]_$post[userid]">$post[reputationdisplay]</span></div></if>
$template_hook[postbit_userinfo_right]
<div>$post[icqicon] $post[aimicon] $post[msnicon] $post[yahooicon] $post[skypeicon]</div>
</div>
</div>
</if>
I've highlighted the <if> and </if> for the condition: $show['avatar']
This means everything in red will only run if the user is displaying an avatar. Notice this includes pretty much the entire userbit, including post count, joined date, messenger icons, infractions etc.
You need to move the bottom <if> up the template so the stuff you want shows whether or not the user has an avatar. ie:
<if condition="$show['avatar']">
<div class="smallfont">
<br /><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$post[avatarurl]" $post[avwidth] $post[avheight] class="avatar-custom" alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a>
</if>
<div class="smallfont">
<br />
<if condition="$post['joindate']"><div>$vbphrase[join_date]: $post[joindate]</div></if>
<if condition="$post['field2']"><div>$vbphrase[location_perm]: $post[field2]</div></if>
<if condition="$post['age']"><div>$vbphrase[age]: $post[age]</div></if>
<div>
$vbphrase[posts]: $post[posts]
</div>
$template_hook[postbit_userinfo_right_after_posts]
<if condition="$show['infraction']"><div>$vbphrase[infractions]: $post[warnings]/$post[infractions] ($post[ipoints])</div></if>
<if condition="$show['reputation']"><if condition="$show['reppower']">$vbphrase[reppower]: <span id="reppower_$post[postid]_$post[userid]">$post[reppower]</span> </if><div><span id="repdisplay_$post[postid]_$post[userid]">$post[reputationdisplay]</span></div></if>
$template_hook[postbit_userinfo_right]
<div>$post[icqicon] $post[aimicon] $post[msnicon] $post[yahooicon] $post[skypeicon]</div>
</div>
</div>
This time, only the red section is ran if the user is showing an avatar, but the code in green is executed either way.
