I upgraded from Tiki18 to TIki24. The site uses the TrackerCalendar plugin (based on FullCalendar). I've been using the "free" (MIT license version) with no issues.
The More info link takes me to https://fullcalendar.io/docs/schedulerLicenseKey#invalid which discusses issues for users of the Premium version. But, as stated above, I'm using the Free (MIT) version.
Anyone else using the TrackerCalendar plugin with Tiki24? How do I set the license type to the free version?
