Facebook is not letting me type, check messages, or anyting else for that matter.

It says that I have two messages, when I click on the messages it shows a blank screne. And when I type in the comment box or my share box it will not take it. And it does not show the list of my friends.

Try another browser if you have access to one (Firefox usually works and solves this problem, or possible a newer version of IE. Also Chrome is usually good). Otherwise see if using a different computer works, again if you have access. If these don't work then it's most likely a problem with FB itself and you just need to wait it out until the programmers at FB work out the bug.
