Unexpected identifier error on tablesorter script - calender selection not working

Hi, the appointments+ plugin is throwing the unexpected identifier error and as a result breaks the calender selection.


It looks like W3 Total Cache is the problem here, but I've disabled Appointments+ self-caching and added the above URL to the Page Cache > Advanced > Never cache the following pages field (followed the directions in the last comment of https://premium.wpmudev.org/forums/topic/appointments-schedule-only-displaying-when-logged-in) but it's still broken.

Please help! Thanks!
