hmm, are you sure you have made everything correct now?
it sounds like it doesn't save the changes to the post
be sure
PHP Code:
$DB_site->query("UPDATE post SET " . $adminsql . "title='".addslashes(htmlspecialchars($title))."',pagetext='".addslashes($message)."',allowsmilie='$allowsmilie',showsignature='$signature',iconid='$iconid'$editedbysql$attachmentsql WHERE postid='$postid'");
is in your editpost.
and i mean the " . $adminsql . " part of it.
if that's not, then i don't know what else could it be.
