I just noticed in the console of my browser that I get the following warnings when I'm on a page where the calendar is present: https://i.gyazo.com/66f7926844ac71699b4fa55c8a761adb.png The calendar works fine, but I thought I'd let you know about the warnings.
Also, is there a way to make the calendar compatible with the MobileFrontend? Currently when a calendar is viewed in the mobile version it seems broken, it doesn't load up. The only possible way to view it is on the desktop version of the wiki.
An other question I have is that is it possible to limit the calendar to be edited by certain user roles. Currently everyone is able to edit it so anyone can vandalize it. I had to manually limit it with CSS.
