you made a mistake in your manual installation

FIND IN postbit_quickedit:
$newpost[message]</textarea>


REPLACE WITH:
</textarea></div>
<div class="smallfont" align="center"><strong>$vbphrase[posting_rules]</strong>:
<phrase 1="misc.php?$session[sessionurl]do=bbcode" 2="$bbcodeon">$vbphrase[vb_code_is_x]</phrase>,
<phrase 1="misc.php?$session[sessionurl]do=showsmilies" 2="$smilieson">$vbphrase[smilies_are_x]</phrase>,
<phrase 1="misc.php?$session[sessionurl]do=bbcode#imgcode" 2="$imgcodeon">$vbphrase[img_code_is_x]</phrase>,
<phrase 1="$htmlcodeon">$vbphrase[html_code_is_x]</phrase>
</div>

you should not remove $newpost[message] in your edit becuase if you try to edit your post it will be blank
