HS2005,
replace the code above with
PHP Code:
<div id="hide_fieldset"><span class="highlight">$vbphrase[sid_hide_post_hide] :</span>
$hide_img
<hr /></div>
if you like to,
but having a fieldset or anything that keeps you (as an mod or admin) keep track on what's hidden and what's not to a user is somewhat important (at least it is most of the times

)
But that only removes the fieldset for hidden images, parsed tags-fieldset is hardcoded to the plugins
stinger2,
wonderful.. a settings-issue (great to know where to look at)
could you export your settings, please?
(delete all security related stuff from the xml right afterwards)
that way I can find the differences to see what setting may be the ugly one
'sid
