Thanks for the responses. From what I found when searching this issue it seems to effect a whole slew of folks. Now that I know it isn't just me it also means that it will repair itself because it is an error on Facebooks' side. Well here's hoping it irons itself out sooner rather than later.
I started having this same problem tonight too. Facebook has been working fine all day - up until about an hour ago. I've heard that Facebook has updated it's privacy settings, and I wonder if that has anything to do with it.
