Page not found on new site

I have WP multisite installed here http://koboland.com/
and a new site at http://koboland.com/insurance/
I published an article on the new site http://koboland.com/insurance/remove-itunes-duplicates/ but when you go to the main site at http://koboland.com/insurance the front page is empty and you cannot see any article.

I did another test at http://koboland.com/test/ and I get an error that "Not Found"

Can anyone help with this?

Thanks
