In all my many posts, I’ve never seen that one. What browser and/or add-ons are you using? I use FF with NoScript, ABP, and CookieSafe, but all of those are turned off for MR. I also allow a permanent cookie for MR. Any chance you have yours set only to allow for session cookies or even temporary cookies on this site? I have seen those settings cause issues when trying to submit information on other sites.
