We've just upgraded to Moodle 3.0.3 using the latest Essentials version 184.108.40.206. Once again, great work on the theme, we have been using the Essentials theme since its creation and always enjoyed the experience.
I've just noticed that in the messages section / page of the theme, after you click on a student to view their message does not appear to be viewing correctly.
The message and response text/comments box has been push completely to the right hand side of the screen making the message unreadable. There appears to be a 'arrow' function that might be intended to push the message section back across to the middle or left hand side however it does not appear to work. See attachment.
Kind regards, Alex Mueller
