Which version are you running - I couldn't see a copyright info for Infopop on your site, so was unsure (you might like to put that back - unless you have permission to remove it)
However assuming you have 6.3....
Yes - it is missing - you have a chunk of code missing around line 245 on the code shown - also above that the code
<span class="small">
<b>{$ubbt_lang['PERMPRINT']}</b>
<br />
$writeperm
~
$replyperm
<br />
$htmlcode
~
$ubbcode
</span>
is different from the original in 6.3
You might wish to grab the original files from the members area and compare them.
at the moment - but expanding all the time....)
