comment out the two lines that have "session_register(xxx)" on them, and add "session_start()" to the page directly under the opeing php tags.  the problem with the header is that it can't perform the action because the warnings are being thrown by the depreciated function and as such there is information being passed to the screen before the header call - which just doesn't work.

it works fine when im logged in on the members page but when i return to the home page the login function resets and it doesnt keep me logged in.

you will need to put the session_start() code at the top of every page you have that will be visited within the session, otherwise the session will be droped.
