Calendar Pro Mocca Calendar

Hello, Do I need to install Calendar Pro extension along with the Mocca Calendar for the recurring events feature?

I suppose you’re referring to https://store.xwiki.com/xwiki/bin/view/Extension/CalendarApplication vs. https://extensions.xwiki.org/xwiki/bin/view/Extension/MoccaCalendar . The first is a fork of the second one, but they are essentially different applications, that don’t depend one on the other. It’s actually not advised to install both. You should chose one or the other.

Ok Thanks
