Because the session you are using probably uses a cookie to remember
the session, it is required that you call session_start before you
output anything to the screen(aka: send any headers). So if you place
the session start at the very top of your page before you include any
files or output anything, the session should work. Beware of any
whitespace before the <?php tags because that will also send headers.
