When I try using either version, I get this:
PHP Code:
<div style="margin:20px; margin-top:5px; ">
<div class="smallfont" style="margin-bottom:2px">Hide:
<table cellpadding="6" cellspacing="0" border="0" width="100%">
<tr>
<td class="alt2" style="border:1px inset">
test
</td>
</tr>
</table>
</div>
EDIT: It looks that the templates are out of date for 3.5.3 when logging into the admin cp.
