Thanks updated

template_php

Code:

<?php

$this->load->view('includes/header');

$this->load->view($main_content);

$this->load->view('includes/footer');

?>

Actual errors... It's failing to bring the pages up at all. When there clearly there

load->view('template', $data); } function about_us() { $data['main_content'] = 'about_us'; $this->load->view('template', $data); } }

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /home/inflscom/public_html/application/controllers/site.php:17)

404 Page Not Found

The page you requested was not found. <-- how can the page not be found when its blatantly there and i presume being summoned correctly?
