I have put off upgrading my Moodle 3.5 because I didn't want to give up Essential, but the time has come. This will be major since I will also need to have my host upgrade the PHP before I can upgrade to the latest Moodle version, and if I understand correctly, Essential will not work after that. Can someone recommend a theme that will make the change in the smoothest, least error-prone manner? I do not know how to go behind the scenes and rewrite code, etc.
Our Moodle site is for adult health education, not kids. Not sure if that matters.
