There can be 2 main reasons why something like this is happening.
First, it can be a browser error. The stale scripts in the browser cache or a new extension interfering in browser operation.
To fix: Log out of facebook. Clear all private data and restore the default settings. In case you are using firefox or chrome, try disabling the extensions or try using another browser. If you are using IE, try using another browser.
Second, the problem can be on the server side, like facebook people updating the code on the server for your area. In that case the problem should get fixed automatically in a day or two.
