I'm trying to do the exercise on chapter 5:Managing Menus. I successfully created the menus and menu items. On the front page I can see the menus but when I click the link other than home, it always gives me Error 404 which doesn't make sense to me since I've setup each menu to open certain categories. I've also created the section, categories, and articles so this error 404 really doesn't make sense in this case.

I run this test on local server using XAMPP.

Any help is appreciated.

Thanks.
