Thanks for answering, that's exactly what I thought, so I tried changing that, but if I do it, then every post shows the 'closed thread' button.
This is the default code in showthread template:
Code:
<if condition="$show['largereplybutton']">
<td class="smallfont"><a href="newreply.php?$session[sessionurl]do=newreply&noquote=1&p=$LASTPOSTID" rel="nofollow">
<if condition="$show['closethread']">
<img src="$stylevar[imgdir_button]/reply.gif" alt="$vbphrase[reply]" border="0" />
<else />
<img src="$stylevar[imgdir_button]/threadclosed.gif" alt="$vbphrase[closed_thread]" border="0" />
</if></a></td>
<else />
<td class="smallfont"> </td>
</if>
Any ideas?
