That’s what happens when you become totally racist.

Seriously, if you use the same browser and version of browser at home and work, it’s possible some newly released javascript is playing badly with that version of the browser’s script engine ... and causing Mr. Browser to think there are no html elements to display - i.e. there may not be an error, but the html the browser is receiving is empty. Unlikely to be that Facebook’s servers are serving you nothing ... although it’s possible. Either way, it will be fixed soon. Refresh, and try different browsers if you need to get on.
