What does this mean?

I was trying to pull a search on my posts, and got this message:

Your submission could not be processed because the token has expired.

Please push the back button and reload the previous window.

What the heck does this mean? I've never seen it before.

TIA for the reply.

I'm guessing that some kind of security token timed out. It was probably a software error. Were you able to run your query after you refreshed?

No, I wasn't, but it's working today.
