An error occurred submitting the answer

Question

I am trying to post an answer to my own question, but I am getting an error message when I try to submit it.

The error message is: An error occurred submitting the answer., which is not a very helpful message.

In the meanwhile I've posted the most relevant bits of the answer as comments against the question, but I would like to post the full answer if possible.

Does anyone have any idea what the problem is?

Answer 1

It must have been a temporary glitch -- I came back later and tried again and it worked just fine.

Nothing to see here, move along please.
