Codeigniter Multi-level Inheritance
I've not seen a multi-level constructor class set up before, but it should work.
Are you calling parent::__construct() in the constructor of each class?
//-Create MY_Controller.php on application/core/MY_Controller.php//contents of MY_Controller.phpclass Application extends CI_Controller{ function __construct(){ // Call the CI_Controller constructor parent::__construct(); }}//that is all now you can inherit class (Application) anywhere in your project
