by (output started at d:\phpweb\website\profile.php:3) in

Three posts and 4all posts the same answer:

You have to put following commands to the very beginning pf your script

session_start();
session_register('username');
session_register('password');

The functions header(), setcookie() and the session functions need to add headers to the output stream.
But headers can only be sent before all other content.
Your script is sending headers after having already sent content,
starting with "<html> <head>..."
