You are opening your session with a specific cache-limiter. This requires
the server to transmit two MIME headers to the client.
header('Cache: none');
header('Pragma: No Cache');
Headers can only be sent _before_ any data gets flushed to the client. In
your source file (change_passwd.php on line 14) some MIME message body data
(web page content) has already been generated and transmitted to the
client, therefore no headers can be sent anymore.
Remedy:
1) don't send data before you're done with the headers, or
2) Use output buffering (ob_start(), ob_end_flush()) to avoid data being
transmitted prematurely.
