CakePHP installation seems to be not working

I got to this page in the CakePHP setup instructions: http://book.cakephp.org/view/1536/Creating-Post-Views

So basically I just created a model, controller and view. Then the instructions say to go to http://www.problemio.com开发者_JS百科/problems/index because instead of their examples with posts, I use "problems"

My setup is like this: rootDirectory/cakephp/app/views/problems/index.ctp

According to the instructions, it should find that index page, but somehow it doesn't.

Is there something I am doing totally wrong here?

Thanks!

It works if you type:

http://www.problemio.com/index.php/problems/index
