note 60902 deleted from faq.using by googleguy

Note Submitter: oldcheesemonkey at yahoo dot com ---- In reference to faq.using: 6. I get the message 'Warning: Cannot send session cookie - headers already sent...' or 'Cannot add header information - headers already sent...'. This can be caused by starting a session and then calling a class function in a php file that has any whitespace either before the very first or after the very last php tags <?php and ?>. Make sure there is NO whitespace before the initial tag and after the closing tag.
