Do you ever get this error message when you post on Hellobee?

We've been tracking down and eliminating errors on Hellobee lately. We just killed one where a weird message kept appearing after some iPhone users posted on Safari: "This topic has been closed." It turned out to be an iOS bug with Safari that we had to workaround... but I think we were able to, and that that bug's dead!

Now onto this one... wondering if anyone gets it. It's only supposed to appear if your post is completely blank when you hit submit... but I think some people are seeing it more often than that.

If you've seen this error, we'd love any details you can remember!
