CodeIgniter Controller breaks when calling parent constructor

I have the following code in helloworld.php:

<?php

class Helloworld extends CI_Controller {

public function __construct()
{
    parent::__construct();
}

public function index()
{
    $this->load->model("helloworld_model");
    $data["result"] = $this->Helloworld_model->getData();
    $data["page_title"] = "CI Helloworld appis";
    $this->load->view("helloworld_view", $data);
}

}

?>

The code stops executing after calling the parent constructor, without giving absolutely any error messages. Nothing appears in /var/log/apache2/error.log either. If I echo something before constructor call, it is echoed. If I type gibberish before the constructor call, a proper error message is printed. Why is this happening?

The site is running on Ubuntu server 12.04 with Code Igniter 2.1.4. and PHP 5.3.

Other files are helloworld_model.php:

<?php

class Helloworld_model extends CI_Model {

public function __construct()
{
    parent::__construct();
    $this->load->database();
}

public function getData()
{
    $query = $this->db->get("data");

    if ($query->num_rows() > 0)
    {
        return $query->row_array();
    }
    else
    {
        show_error("Database is empty");
    }
}

}

?>

And helloworld_view.php:

<html>
<head>
    <title><?php echo $page_title ?></title>
</head>

<body>
    <?php foreach($result as $row): ?>
        <h3><?php echo $row["title"]?></h3>
        <p><?php echo $row["text"]?></p>
        <br />
    <?php endforeach ?>

</body>
</html>

As far as I understand, the Controller constructor is what gets called absolutely first, so I don't think the rest of the files matter at this stage(?).

I had same problem that was resolved by changing 'dbdriver' => 'mysqli' to 'dbdriver' => 'mysql' in you config/database.php. Also make sure your database connection parameters are correct.

My guess, and I would have to see your configs to be sure, is that there is a problem in the initialization of your Loader. Most commonly this has to do with the automatically loaded libraries, and sometimes it has to do with a bad database configuration. My first suggestion would be to try to get something working using the default configs. If that works, then you have a good starting point.
