@sms1114,
It looks like something on their end. I can log in, so I went to their community help center and quite a few people are having the same issues.
Those that are posting about the problem are posting from their cell phones because they can't log in from their computers. You won't get anyone on the phone but Facebook is responding to some of the comments but Facebook isn't telling anyone what the problem really it, could be some hacking going on they don't want people to know about.
All Facebook is doing is posting the same comment to those that can't log in.

Hi Deann,
Can you give more detail about what you see when you try to log in? Have you taken a look at the login section of our Help Center?
