parent::Controller();
}
function index()

$this->load->helper('url');
$this->load->library('session');
$this->load->model('Do_Login');
$query = $this->Do_Login->checkLogin();
$num_rows = $this->db->affected_rows($query);
if($num_rows > 0){
$row = $query->row();
$newdata = array(
'user' => $row->nome,
'empresa' => $row->empresa,
'email' => $row->email,
'logged_in' => TRUE
);
$this->session->set_userdata($newdata);
}else{
$newdata = array(
'user' => 'failed',
'empresa' => 'failed',
'email' => 'failed',
'logged_in' => FALSE
);
$this->session->set_userdata($newdata);
}
if($this->session->userdata('logged_in') == TRUE){
redirect('index.php/environment/'); # index.php/login/
}else{
redirect('index.php/welcome/'); #index.php/welcome/

check every file that gets loaded automatically, and any file you may have edited. like config.php, database.php, index.php

Check for whitespace outside of the <?php ... ?> tags in login.php.
