Moodle 3.7.2 - Single simple discussion forum type (although I can re-create error on standard type as well).
For admin the inline reply works fine.
For student, the Submit button does not respond with following js message in console
The advanced reply works.
Firefox: TypeError: j.find(...).get(...) is undefined3 first.js:162:990
Chrome: VM30 first.js:162 Uncaught TypeError: Cannot read property 'value' of undefined at HTMLButtonElement.<anonymous> (VM30 first.js:162)
Any ideas on how to fix this?
