404 The Content you are looking for is not available

After a reboot, my site stopped serving the main page content. I have found that some were able to fix this by re-saving permalinks. This did not work for me. I have looked under my widgets, and all the content appears to be there. I looked under settings/ reading and it is set for static and the page is "About Us." Help appreciated you may view my problem at wisrd.org
