会话毁坏Codeigniter中的问题

I am facing for the first time a new issue with session destroy. Before today when I would click on the logout using this:

 function logout()
 {  
      $this->session->unset_userdata("logged_in");    
      $this->session->sess_destroy();      
      redirect(base_url(), 'refresh');
 }

That session was easily destroyed, but today it is not working. This is the code where I start the session.

function checkDataBase()
    {
        $this->load->library('session');
        $email    = $this->input->post('email');
        $password = $this->input->post('password');
        $result   = $this->login_model->contractor_login($email, $password);
        //    die;
        //  echo "<pre>";print_r($result);die;
        if ($result) {
            if (isset($_POST['remember'])) {
                $this->input->set_cookie('email', $_POST['email'], 3600);
                $this->input->set_cookie('password', $_POST['password'], 3600);
            }

            foreach ($result as $row);

            $role_id = 2;

            $session_data = array(
                 'id' => $row->id,
                 'name' => $row->name,
                 'country_id' =>$row->country_id,
                 'category_id' =>$row->category_id,
                 'company_name' =>$row->company_name,
                 'email' =>$row->email,
                 'address1' =>$row->address1,
                 'counties' =>$row->counties,
                 'phone_number' =>$row->phone_number,
                 //'business_status' =>$business_status,
                 'role_id' => $role_id

            );
            $this->session->set_userdata('logged_in', $session_data);
            return TRUE;
        } else {
            $this->session->set_flashdata('message', 'Wrong Username or Password');
            redirect("contractor/login");
        }
    }

    From the Codeigniter Session Class documentation, regarding Flashdata we can read:

    CodeIgniter supports "flashdata", or session data that will only be available for the next server request, and are then automatically cleared. Your problem might be that when you redirect, the process takes more than one request, clearing your flashdata.

    To see if that's the case, just add the following code to the constructor of the controller you are redirecting to:

    $this->session->keep_flashdata('message');
    

    This will keep the flashdata for another server request, allowing it to be used afterwards.
