The Chat plugin is not working since update

Since the recent update of WordPress 4.8. The chat plugin is not working as it should. The chat shortcode doesn't work from the text editor and in the front end.

Also, note that I had to uninstall and reinstall chat to work again. I am also currently using a hotfix provided by the wpmudev team.
