Try to add these lines at the constructor class:

Code:

function __construct()
{
   parent::__construct();
}

EDIT:
I think the real problem is a naming problem: Both Model and Controller have the same name "User". Change one of them and it might work.[/quote]

The model is named 'User' and the controller is 'Users' (plural).

I've added the construct function, but I still get the same error:
Fatal error: Call to undefined function User()

It seems like it must be something with the Autoload? There is no User() function, except for what would be mapped to an object from the model
