The previous page improperly used a trial version of a plugin that requires a Club GreenSock membership. That file only works on certain domains like codepen.io. See https://codepen.io/GreenSock/full/OPqpRJ/ for a full list of trial URLs.
Club GreenSock members can download unrestricted versions of the bonus plugins from their account dashboard anytime. If you're not a member yet, what are you waiting for? Animation superpowers await! Sign up today.
