Calendar only click on item not in blank field

Hi There,

I have a calendar for fifferent users. User can view the calender item by clicking on it.
if a user clicks on a calendar space where there is no item, a popup also appears, i wan’t that disabled so a user only can click on an item and else nothing happens. any suggestions?

I have done this but think you should give them edit and not create access. Are you using the security application

Yes indeed. Ik went from 5.6 to PHP 7 some code must be changedto het it working. DayClick in calender code should be dateClick. For example. Ik Will try your tip. Thx
