Whatever it is on line 2 of assessresult.inc.php that is causing output
to be started!
More seriously, there is something on line 2 of that file that is
causing something to be sent to the browser, which in turn causes the
http headers to be sent. Once those headers have been sent, nothing else
that wants to send headers, which includes starting the session and
setting cookies, can be done.
Either eliminate whatever it is on line 2 that is sending output, or
move the session_start() and/or setcookie() calls above it. (This early
in the file, prime candidate is actually a stray blank line outside your
<?php tag, but that's only a guess based on past experience of many
people in this list...!!)
Cheers!
