¿has hecho algún cambio en el postbit?
postbit tiene este code:

{$ignore_bit}
<a name="pid{$post['pid']}" id="pid{$post['pid']}"></a>
<table border="0" cellspacing="{$theme['borderwidth']}" cellpadding="{$theme['tablespace']}" class="tborder" style="{$post_extra_style} {$post_visibility}" id="post_{$post['pid']}">
<tbody>
<tr>
<td class="tcat">
<div class="float_left smalltext">
{$post['postdate']}, {$post['posttime']} <span id="edited_by_{$post['pid']}">{$post['editedmsg']}</span>
</div>
{$post['posturl']}
</td>
</tr>

<tr>
<td class="trow1 {$unapproved_shade}">
<table cellspacing="0" cellpadding="0" border="0" style="width: 100%;">
