CUNY Academic Commons

Ray, could you have a look? I think this one has to be coupled with other updates.

I've updated the-events-calendar from 6.10.2 to 6.11.1, event-tickets from 5.20.1 to 5.21.1, and events-calendar-pro from 7.4.2 to 7.4.3 in: https://github.com/cuny-academic-commons/cac/compare/a377002...7b64671.

Just a FYI for Matt, the Events Calendar Pro license has expired so we will not be able to update to the next release going forward.
