Chat Plugin not Working for non-admin

Hello
I've installed Chat and I think I have set it up correctly (BTW- How about a user guide? SO many options and no idea what they all are) however it is not showing up in the footer widget where I put it for authors. I only have an author and an admin so far and it is showing on admin.
In Authentication I have ticked Author and in WYSIWYG Chat button User roles I have ticked Author. What am I missing?
