I'm working joomla on my home computer. I created several sections, categories and articles.

I went to menu manager, clicked on main menu, created a new link and selected the article from the list shown, when I refresh I get the new menu item but when I click on the item iget the following:

Object not found!

The requested URL was not found on this server. The link on the referring page seems to be wrong or outdated. Please inform the author of that page about the error.

If you think this is a server error, please contact the webmaster.

Did I mess up during installation of the joomla site?
