Blank page for Email test

[eluser]webnology[/eluser]
Hi Bobbafoley,

thx for helping. I've added the rule, but still no results. Empty, white, blank page. No mail is sent. No errors.

Thsi is my full contrller, maybe you see sth wrong?

Code:

<?php

class Cron extends CI_Controller {

    //Constructor
    function __construct()
    {
        parent::__construct();
        
        $this->load->model('m_customers');
        $this->load->model('m_settings');
        $this->load->library('email');
    }
    
    function index() { }
    
    function sendTestMail() {

        $config['protocol']  = 'smtp';
        $config['smtp_host'] = 'host';
        $config['smtp_user'] = 'user';
        $config['smtp_pass'] = 'pwd';
    
        $this->email->initialize($config);

        $this->email->from('[email protected]', 'Sender');
        $this->email->to('[email protected]');
        $this->email->subject('Subject');
        $this->email->message('Test');
        $this->email->send();
        
        echo $this->email->print_debugger();  
    }
}
