Wrong post displays

Hello, I have setup a newrooms in a site: http://212.241.193.198/about/news-events/

Background: I have recently changed the default directory of wordpress and also changed permalinks. I added the htaccess file with appropriate permissions. That seems to be when my problems started.

Problem: When you click a headline, instead of seeing the full story, you see the most recent post. When I add a new post, that becomes the post that is displyed when you click the headline of any other post. Any ideas?
