Blog not showing all posts, links, archives

New WP blogger using Yahoo! Hosting. Published several posts after installing blog to be shown at url https://www.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?
