Error when posting: "The message body was left empty."

[EndersGame]

I tried making a post in Playing Card Plethora, and got the following error, even though the message body is clearly not empty.

It turns out that somewhere in that message I had the incorrect code [ /inlineimg ] instead of [ /img ].  Fixing that allowed it to post.

Still strange that the error it produced was "The message body was left empty", when it clearly wasn't.

The incorrect code added may have rendered the message body as unseeable, therefore it was considered blank.
