There is a link in clippy.min.js to an external agents folder that is no longer active. This makes this js unable to display any agent. The latest link in this js is set to "clippy.BASE_PATH="//s3.amazonaws.com/clippy.js/Agents/", which is dead. To resolve the issue, download the agents folder from Github and edit this clippy.BASE_Path reference to point to the location of that downloaded folder on the local machine, or host it on a reliable external server and point it to there.
