I just got a very wired error. I have the editor in a popup page. When I click on a radio button, it should popup the page with editor. Every first time, it's ok to get the editor. However, after the first time, if I try it again, it will give following error message. I have no problem when I debug it in my development environment. It only happens when I deploy it to server.
Can you please give me some adivce what the error msg means.]
