Codeigniter blank page when load database

Question

So after while searching into stackoverflow, decide to write this question.

I'm working this time on Godaddy's hosting cPanel plan. Uploaded a clean package of Codeigniter V 2.2.6 and the welcome message shows as it should. I configured config.php with url and database.php with the correct connection data. Until now, everything work as it should. So after that load database to see if everything goes bien and the "blank screen of dead" appears if I refresh the page.

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

class Welcome extends CI_Controller {

    /**
     * Index Page for this controller.
     *
     * Maps to the following URL
     *      http://example.com/index.php/welcome
     *  - or -  
     *      http://example.com/index.php/welcome/index
     *  - or -
     * Since this controller is set as the default controller in 
     * config/routes.php, it's displayed at http://example.com/
     *
     * So any other public methods not prefixed with an underscore will
     * map to /index.php/welcome/<method_name>
     * @see http://codeigniter.com/user_guide/general/urls.html
     */
    public function index()
    {
        $this->load->database();
        $this->load->view('welcome_message');
    }
}

/* End of file welcome.php */
/* Location: ./application/controllers/welcome.php */

So after searching where it breaks, I found inside /system/core/Codeigniter.php in lines 300. Break before $CI = new $class();

/*
 * ------------------------------------------------------
 *  Instantiate the requested controller
 * ------------------------------------------------------
 */
    // Mark a start point so we can benchmark the controller
    $BM->mark('controller_execution_time_( '.$class.' / '.$method.' )_start');
    $CI = new $class();

And Inside the log files, returned this lines

I need to deploy a web made in other server and when I uploaded inside Godaddy the blank page appears, that's the reason why I upload a clean package of Codeigniter. Anyone can help me? Thanks in advance.

EDIT Forgot to write the error report on index.php

define('ENVIRONMENT', 'development');

if (defined('ENVIRONMENT'))
{
    switch (ENVIRONMENT)
    {
        case 'development':
            ini_set('display_errors',1);
            error_reporting(E_ALL);
        break;

        case 'testing':
        case 'production':
            error_reporting(0);
        break;

        default:
            exit('The application environment is not set correctly.');
    }
}

Load database Library in application/config/autoload.php like follows:

$autoload['libraries'] = array('database');

Remove following line from your file:

$this->load->database();
