Why is Facebook being glitchy right now?

[john]

Every time I try to comment on anything I get this:

The content you requested cannot be displayed right now. It may be temporarily unavailable, the link you clicked on may have expired, or you may not have permission to view this page.

But when I refresh, my comment shows up fine. This is mostly happening when pages post pictures and stuff.
Okay, so when I comment using my profile, it's normal. This error only appears when I try to comment on Facebook as one of my pages. Though my comments do get posted, it's kind of annoying seeing this message.
