Yahoo Hosting Error- Blog Not updating

New WP blogger using Yahoo! Hosting. Published several posts after installing blog to be shown at url moseleyworld.com. 1st few posts worked fine but after the latest post, WordPress began showing only the last post but no second-column items like archives, links, previous posts, etc.

So, I de-activated the blog and started over…but the same thing is happening! The index.php file shows a last-updated date of 8.30 but i added the posts 8.31.

Can someone please help this newbie?
