OJS3, bug when changing discussion contents

Hi there.

I tried to change the contents of one of the messages in the Copyediting discussion section. An error occurred and I ended with white screen showing this message:

{“status”:true,“content”:"",“elementId”:“0”,“events”:[{“name”:“dataChanged”,“data”:[“2976”]}]}

Is this a bug?
Thanks

check your php error log, do you see a fatal error there?

Can you reproduce the same error every time you try to edit?
