What does this mean on facebook?

Could be numinous reasons why its stopped you getting access, Like the once you just said your name is blocked in there private setting so you cant see anything. The sever could be timing out check the pings and tracert in cmd to Facebook also to see how many millosec's from you to your sever eg facebook.co.uk and count the hop's. Check for malware or virus's these could be an issue and redirecting you away from the sever. Clean your cache and history up also some might be causing problems there. But main question is if you know the person give them a call and ask why you cant get access.. Check to see if there still in your friends list.
