Vel Posted April 11, 2011 Share Posted April 11, 2011 ob_start() doesn't start your session. It starts buffering to stop any information other than headers being sent. You need to use ob_end_flush to release the buffered information. But as you want to initiate the session at the top of the script you don't need ob_start() at all AFAIK. Just replace ob_start() with session_start(). EDIT: I see you've put your code at the top that's why you have ob_start(). Why is all your code at the top of the page and not in the body section?
