We don't even see a 'replay' controller function? What are we missing?

Sounds to me like if a user logs out, they are logged out and shouldn't have access to the admin functions. So where exactly is the problem?

Replace

Code:

$this->session->unset_userdata('login');

with

Code:

$this->session->sess_destroy();

There might be parts of the session he wants to maintain.

[eluser]mglinski[/eluser]
Then why not save those parts in an array from the current session, destroy the old one, and then create a new one? The removal function does not seem to be working as expected.

The removal function works fine. If you don't think so, try it out yourself. If you can produce a case where it fails, show us. The problem, I believe, is elsewhere. We're just having a bit of trouble communicating to get at that place.
