Individual Post Pages Wont Appear

So I was playing with my databases and now individual post pages wont show. You can see them on the home page: https://www.snipbids.com, but when it go to an indivdual post page like the one pasted below, i get a 404 error. Pages work just fine. I have forwarded some posts to another section of the site til this is fixed.

Any help would be greatly appreciated
