CI 4 simple session auth system problem

Remove the following line from BaseController. It is not needed because the session library does this for you.

PHP Code:

$this->session->start(); 


That may be the reason $this->session is coming up null.

---

Try this change for loggedIn()

PHP Code:

protected function loggedIn()
{
    if ($this->session->has('loggedIn'))
    {
        return redirect()->to(base_url('dashboard/index'));
    }

    // then not logged in
    return redirect()->to(base_url('auth/index'));
} 


Then you can remove public function notLoggedIn()
