Multiple Controllers

[eluser]smilie[/eluser]
Well, try this:

class NSBA_Login extends Controller
filename: NSBA_login.php

Change filename to NSBA_Login.php

Not sure, but I think I read somewhere that it looks for exactly same name (lower / upper case).
Also, try to use different controller / file name, just for the test i.e. Abccontroller -> Abccontroller.php

Good luck.
