having confusion with ob_start()
<p>so i have a file, that loads content from another file. both these files require a file that connects to db, the connection file at the top has ob_start(), and under that, session_start(), fine. When i view the parent file (that loads content (using JS) from another file) i get:</p>

<blockquote>
  <p>Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/xxxx/public_html/child_file.page.php:1) in /home/xxxx/public_html/connection.inc.php on line 3</p>
</blockquote>

<p>so then in the child file i put ob_start() at the top, but there was still the error?</p>
