get_instance now NULL in MY_Exceptions [CI 3.1.5]

Probably not the most elegant solution but we do a redirect to our error controller.

PHP Code:

<?php if ( !defined( 'BASEPATH' ) ) exit( 'No direct script access allowed' );

class MY_Exceptions extends CI_Exceptions {
    /* public methods */

    public function show_404( $page = '', $log_error = true ) {
        header( 'Location: https:/error/404' );

        exit;
    }
}

?>
