Its probably because you are using extra segments in the urls for News and Classified. your News page has siteroot/onlineportal/newshome.aspx, the extra segment in the url is not supported. The friendly urls were not designed to act like folders, it is designed for short urls, you should remove "onlineportal/" from the url.

Also your home page has the url "default.aspx", you should give it the url ~/home.aspx, you cannot use default.aspx as a friendly url, the first page in the site will be shown for default.aspx, so if you move News to be first it should be shown for default.aspx but because you have that url attached to home it is a problem.

Default.aspx is the physical page that serves all pages in the menu, so you should never assign that as the url of a page.

Friendly urls all map to /Default.aspx?pageid=x as the real url so you can't use Default.aspx as a friendly url.

Hope it helps,
