hello i downloaded the v.2.11.0 version of mautic. I have an error. When I try to create a reply email to my subscribers. I design the mail, but when I try to save it. He does not want. Here is the errator in the chrome console [lien vers l’image](http://prntscr.com/hattin); That he has encountered the same problem?
