You need to see that no output from the PHP pages is generated before you use
the session, eg

---start of file---

<?PHP
...
?>
--- end of file ---

This page wouldn't work for sessions, as there is a newline on it.
You should run session_set_cookie_params() if your default settings aren't
okey, the broken browser (MSIE) has problems if there hasn't been a domain and
path set.
