"headers have already been sent" means that output has been sent to the client. Cookies, meta data, sessions and things of that sort can not be modified after the output has already been sent. Make sure that anything which modifies it is
the first bit of output.
I tend to avoid sessions, they are too often unreliable, especially in larger environments that are not managed by pros.
