SOLVED: CI 4.0.2 and subdirectories

You need to namespace all folders and sub-folders.

If in the Controllers directory then:

PHP Code:

<?php
namespace App\Controllers; 


If the Controller is in a sub directory:

PHP Code:

<?php
namespace App\Controllers\sub-directory; 


When extending or using a Controller from a sub directory:

PHP Code:

use App\Controllers\sub-directory
