Hi,

This message means that your script has already output something before the cookie information is sent.

Often this is caused by a notice/warning that PHP is sending. Try putting:

as the very first line of your script and see if PHP then shows the errors.

Also, check that config.php isn't sending any output (even a blank space/line) and make sure that "display_errors" is set to true in your php.ini (if you have access to it)
