Posts not showing up, “Archives” displayed on home page

All of a sudden my site is not displaying any of the posts/custom posts types. When you visit the site ne-pos.com, all you can see are the header and the footer directly underneath it (not where it’s supposed to be. If you try to scroll, the word “Archives” is displayed on the page. Since none of the posts appear, the header menu is not functional. It was a one-page site with all the posts appearing as fluid sections. Please help!
