I'm trying to load a view from outside the application folder in Codeigniter (3.1.0) like this:

```
public function index ( $page = '' ) {
    /**
     * Get active theme from DB
     */
    $active_theme = $this->m->getActiveTheme();

    /**
     * Change default view path
     */
    $this->_ci_view_paths = array(
        FCPATH . 'themes/' . $active_theme . '/' => TRUE
    );

    /**
     * Load index if page is not found
     */
    if ( ! file_exists( FCPATH . 'themes/' . $active_theme . '/' . $page . '.php')) {
        $this->load->view( 'index', $data );
    } else {
        $this->load->view( $page, $data );
    }
}

```

But I'm getting this error:

Unable to load the requested file: index.php

Or whatever page I try to load.

Anyone know what I'm missing here?
