I'm trying to sign into facebook but it keeps saying that it cannot register me, what should i do?
Try delete history and data, delete cookies, clear the cache and check on your pass word. If you are on fire fox try internet explorer. If that still doesn't work. Visit http://www.facebook.com/help for more help.
Or someone hacked it.
U r going to have to delete ur account and make a new one that has happened to me
