You have some wacky things happening in your site… unfortunately you will need to try and backtrack what you did from the point of when they were working. But I see your home page with no post/page content but I see comments there (not sure if this is what you wanted), but I also noticed that if I click on any of the “Recent posts” from the widget, I get a totally blank page. So you have something wrong somewhere. I would also recommend changing your permalinks to the default setting and see what happens.
