How can I remove the chat widgets from pages and from forms
If you cleared the Portal Cache (re-previewed the site or manually using _services/about )
check if Co-Pilot has been added, in the Power Pages designer, edit the Site and go to Setup in the left hand menu, and then check if Co-Pilot has been added and enabled.
How can I remove the chat widgets from pages and from forms
In the Portal/Power Pages Management App, you should find a Content Snippet called something like "Chat Widget Code" clear its contents (this is what gets included on every page - haven't done a chat in a long time but don't remember it being on Basic Forms also).
