Kalo dari pesan errornya sepertinya sudah ada output yang dikirim ke client sebelum fungsi session_start dipanggil. Kalo memang mau pake panggil, sebaiknya ditulis di konstruktor. 

class Welcome extends Controller {
         function Welcome() {
                parent::Controller();
                session_start();
         }
}

Selain pake cara konvensional pake $_SESSION variabel, kamu bisa pake Session library yang ada di CI. Coba deh. Contohnya sederhananya begini:
class Welcome extends Controller {
         function Welcome(){
                  parent::Controller();
                  $this->load->library('session'); //mulai session
         }
}
 
//--------------------------------- 
 
//cara pake
$this->session->userdata('nama'); //ngambil data dari session
$this->session->set_userdata('nama', 'syabac'); //nyimpen data ke session

Di CodeIgniter nggak perlu session_start()

Di CodeIgniter nggak perlu session_start().

Kebetulan baru jawab pertanyaan yang mirip. Baca disini: https://www.codeigniter-id.com/node/173

Untuk mengakses session.
Ganti

$_SESION['namasession'];

menjadi

$this->session->userdata('namasession');

Ngeset session

$_SESSION['nama_session'] = "Hahahaa";

Ganti menjadi

$this->session->set_userdata('nama_session', 'Hahahaa');
