Random Access Denied

I think it's running in a linux instance. Apache version 2.4 and PHP version 5.5.

This is the controller PainelDeControle.php:

Code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class PainelDeControle extends CI_Controller {

 public function index()
    {
   $this->load->helper('myhelperacesso');
   if (usuarioLogado()) {
     $this->load->view('templates/header.php');
     $this->load->view('templates/headerPainelDeControle.php');
     $this->load->view('templates/menuHeaderPainelDeControle.php');
     $this->load->view('painelDeControle/index.php');
     $this->load->view('templates/menuFooterPainelDeControle.php');
     $this->load->view('templates/footerPainelDeControle.php');
     $this->load->view('templates/footer.php');
   } else {
     $this->session->set_flashdata("mensagem-fracasso", "Acesso negado. Nenhum usuário logado.");
   
     $this->load->helper("url");
     redirect(base_url("index.php/usuario/entrar"));
   }
    }
}

?>

In the index() function the else statement is executed, because there's no user yet defined.
