CodeIgniter 2 - captcha helper?

The problem was in the path's for images. One thing, even with the log threshold set to four, I was getting NO indication of any kind of problem. I set it to absolute paths and everything worked fine...

    function index()    {           $this->load->helper('form');        $this->load->helper('captcha');        $this->load->model('captcha_model');        $vals = array(            'img_path'   => '/var/www/mysite.com/images/captcha/',            'img_url'    => 'http://mysite.com/images/captcha/',            'font' => '../../system/fonts/texb.ttf',            'img_width'  => '150',            'img_height' => 30,            'expiration' => 7200,            "time" => time()            );        $data['cap'] = create_captcha($vals);        $cap = array(            'captcha_time'  => $data['cap']['time'],            'ip_address'    => $this->input->ip_address(),            'word'   => $data['cap']['word']            );        $this->captcha_model->add_captcha($cap);        $data['main_content'] = 'admin/landing.php';        $this->load->view('includes/template', $data);    }
