After upgrading my Debian server to jessie (8.0) and roundcube to 1.1.1 I am no longer able to send mail using roundcube. After composing a message, pressing 'Send' simple does not do anything and the compose window remains. According to the logs there is no communication with the mailserver yet, so I suspect more of an interface/javascript issue.
Nothing is written in the logs when pressing the button.
In developer mode (firefox) I see javascript errors: TypeError: this.editor is undefined1 app.js:3672:8
