PHP Problem: User won't stay logged in.

[Lukeidiot]

On my member system located at: http://lukeidiot.com/vip
It will let you login and it say's "Thanks for logging in: 'Username'."
But when you try to goto the "Control Panel" it says "You need to be logged
in to do this.

Now I know this isn't an error in the coding of the script because the previous
php member script I used did the same thing. Any idea on why this is happening?

Thanks Futurely.

do you have session_start() on the top of the page?

Yeah, it says "ob_start();" which i believe means the same as "session_start();".
I get this error in my sites Cpanel's "Error Log":

[Fri Sep 14 13:37:23 2007] [error] PHP Warning:  Cannot modify header information - headers already sent by (output started at /home/wwwluke/public_html/vip/index.php:4) in /home/wwwluke/public_html/vip/members.php on line 144

no. ob_start starts output buffering. You need session_start which will start the session.

It would help to see your code in order to debug it. It sounds like you are not properly setting your session or cookie variables (depending on what method you are using).

Can you post the same code that sets up these variables?
