Have you installed any Blocker type apps since you last had to sign into FB?
I installed PeerBlock for Androind and got the same FB message when I had to sign back in.
Turned off "Block DNS" and all good

The most recent Facebook update is just horrible. Since updating whenever I logon it takes minutes for anything to update. I just get the update circle. I don't know what's going on but then again Facebook has always been a really crappy app anyway, but they seem to have outdone themselves this time. Hopefully there will be another update fixing these problems soon.
