Gisler,

Without knowing what is within your other includes I would say that you either have have a session_start() being executed in your functions.php file or some type of other output. The safest bet is to make sure that session_start() is the first method executed; include or execute it separately at the very top of your script. Separating it as another include or even creating a session class will also help you in the long term should you decide to start adding more features to your session handler.
