does anyone know? Why do I sometimes get: Done, but with error on page? FACEBOOK?

[ET]

When I am on Facebook, sometimes while playing games (Island Paradise) I get a message at the bottom of the page: done but with error on page. when this happens, my computer usually freezes up. I have to do ctrl alt delete to get out. This only happens sometimes. Would this be my computer, or Facebook?

It would be a script error for whatever Facebook app you are on.
Usually associated with Javascript.
Once the developers of that app etc have fixed the problem the message will disappear.
It's not your computer.
