Those error messages are caused by those pages trying to send headers,
probably cookies for php sessions when headers have already been sent. 
When the server returns a php page, it doesn't finish the headers off
until the first line of content is returned, this allows the php script to
add headers to be sent.  The problem you are running into is probably
comming from the php open tags.  PHP has several methods for starting off
the PHP in the file (<?php <? are the most common).  What most likely is
happening is you don't have short tags turned on meaning that only <?php
works.  When the PHP script engine sees the <? it assumes this is content,
the headers are finished off and the following text is sent to the
browser.  The reason your page is incomplete could be that some of the
page should have been generated by the script.  Something you could try
doing is setting the short tags option on in the PHP settings file.  Add
or set the following line in /etc/php.ini:
short_open_tag = On
see if that doesn't help you out.

I may be totaly off base but it is worth a shot.
