Sometimes when trying to post a Youtube video, I get this error message, and then sometimes I have no problems at all. I am curious as to why I keep getting it, and if anyone else has experienced the same problem.

I've gotten this before, actually, and off the top of my head I have no clue why it's doing that.

If that happens again, would you try typing something under or above the Youtube code, posting, and then try to edit whatever you put in with the Youtube code out? I'd like to see what happens.
