session_start() must be called before ANY OUTPUT - including whitespace,
DOCTYPE statement, <head>, etc. 99% of the time people ask about
session problems here, they have already sent output before the call to
session_start() is made, but don't have error reporting enabled.
As the very first lines in the page you're loading, try the following:
<?php
error_reporting(E_ALL);
ini_set("display_errors","1");
?>
No whitespace or anything else before it.
