You have an error in the code:

<if condition="THIS_SCRIPT=='private' && is_member_of($post, INSERT YOUR MOD USEGROUP ID's">
<table table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>
<td class="alt1" width="30"><img src="$stylevar[imgdir_misc]/verified.gif" width="44" height="39" alt="Verified!" /></td>
<td class="alt2"><strong><font size="2" color="#339900">V E R I F I E D</font></strong><br /><font size="1">This message was sent by an official <strong>$vboptions[bbtitle]</strong> staff member. It's contents can be trusted.</font></td>
</tr>
</table>
</if>
<if condition="THIS_SCRIPT=='private' && is_member_of($post, INSERT UNVERIFIED USERGROUP ID'S">
<table table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>
<td class="alt1" width="30"><img src="$stylevar[imgdir_misc]/unverified.gif" width="44" height="39" alt="Verified!" /></td>
<td class="alt2"><strong><font size="2" color="#0f4390">U N V E R I F I E D</font></strong><br /><font size="1">This message is from someone other than a staff Member. If it contains spam please report it to the forum <a href="INSERT YOUR FORUM URL/private.php?do=newpm&u=1">admin</a>.</font></font></td>
</tr>
</table>
</if>
</if>

The fix is easy:

<if condition="THIS_SCRIPT=='private' && is_member_of($post, INSERT YOUR MOD USEGROUP ID's)">
<table table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>
<td class="alt1" width="30"><img src="$stylevar[imgdir_misc]/verified.gif" width="44" height="39" alt="Verified!" /></td>
<td class="alt2"><strong><font size="2" color="#339900">V E R I F I E D</font></strong><br /><font size="1">This message was sent by an official <strong>$vboptions[bbtitle]</strong> staff member. It's contents can be trusted.</font></td>

</if>
<if condition="THIS_SCRIPT=='private' && is_member_of($post, INSERT UNVERIFIED USERGROUP ID'S)">
<table table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>
<td class="alt1" width="30"><img src="$stylevar[imgdir_misc]/unverified.gif" width="44" height="39" alt="Verified!" /></td>
