Call to undefined method VI_Loader::_ci_load_class()

I am try to update a site from CodeIgnitor 2.2.2 to 3.1.6

I am getting

Line 152 is

$this->_ci_load_class($library, $params, $object_name);

VI_Loader is under the core library


cand start with

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

/* load the MX_Loader class */
require APPPATH."libraries/MX/Loader.php";

class VI_Loader extends MX_Loader {



Why can't it find it? Any ideas please


Thanks

I downloaded the latest MX in the end

The are all kinds of patches on the forums here to fix bugs in the HMVC so you need to search.
