Answer 1

This error can occur if the wrong default prefix is set in the config file. Open application/config/config.php and change the line

$config['subclass_prefix'] = 'MY_'; to: $config['subclass_prefix'] = 'REST_';

Let me know if this doesn't work and I will try to update my answer and help you further.

Before declaring your class, try this:

    <?php
    defined('BASEPATH') OR exit('No direct script access allowed');
    require APPPATH . 'path/to/REST_Controller.php';
    class Apie extends REST_Controller {
        function __construct(){
        ...
        }
    }
