mostly stupid issue,
I’m not able to create an event in the calendar, I get this error message : Access denied when checking [programming] access to [ohmb:MoccaCalendar.MoccaCalendarEventValidation] for user [xwiki:XWiki.Benoit]
other apps (blog …) are ok
cannot figure out whether I missed something / wrong handling or whatever
Looks like the Calendar application require the author of the page MoccaCalendar/MoccaCalendarEventValidation to have programming right, I just fixed it (re-saved the page). I’m not a Calendar app expert so it’s possible other pages need to be saved by someone having programming right.
