1.6 Default Route

[eluser]JWarren[/eluser]
Can some tell me what I'm missing?

I was moving an unfinished project from CI 1.54 to 1.6 and my default route quit working. After fighting with that for a few minutes, I downloaded and extracted a fresh copy of 1.6.

http://localhost/CodeIgniter_1.6.0/index.php/ == 404

http://localhost/CodeIgniter_1.6.0/index.php/welcome/ == Welcome to CodeIgniter

Obviously, since this is a fresh copy routes.php contains

Code:

$route['default_controller'] = "welcome";

So, what am I missing?

Thanks in advance.
