A GOOD and versatile news manager needed

[andyash]

In your modified News Manager that I just downloaded and tried out, The categories from the sidebar aren't working. When I click on a category a message says "Oops! Page not found! We are sorry, but the page you are looking for does not exist."

Why is it there? I know for sure I created two categories and put one post in each. The main blog page shows me both post excerpts and clicking on them takes me to the post. The Recent Posts, Blog Archive links are all working fine. Only the Category one doesn't.
