Answer 1

Try on your admin controller
public function __construct() {
parent::__construct();
if($this->session->userdata('loggedIn') == FALSE){
redirect('alogin');
}
$this->load->model('user_model');
$this->load->model('admin_model');
$this->load->library('form_validation');
$this->load->library('session');
$this->load->model('articles_model');
$this->load->helper(array('form', 'url'));
}
And change on your session check ! to FALSE and move it to the top like shown
Also try and var dump sessions just to make sure working.
echo '<pre>';
echo print_r($this->session->all_userdata());
echo '</pre>';

Answer 2

just check the user session in constructor of each controller
in your controller where you are saving session ..?
first of all make a method in base/parent controller to check the user is login
then call it in each controller's constructor
you can check all stored session through below given method
$this->session->all_userdata();
