how many levels of subfolders are supported ?

[eluser]AtlantixMedia[/eluser]
as I said, I use exactly the same method in other parts of the application and it works great.

Adm extends Controller
Main extends Adm
Config extends Main

Adm takes care of access level checks (permissions, etc)
Main hold several common functions used by the Admin section and displays the admin main page
Config takes care of specific configuration functions

also, I get the same 404 error if Config extends Controller
