Hi staevenfrey,
Thanks for posting.
If you’ve configured the calendar widget to list 0 events below the calendar grid itself then yes, day view must be activated if you want it to link to days containing events. Day view does not have to be the default view, though (just in case there was any confusion on that end).
I’m a bit puzzled as you note having activated day view without success – so I’d love to take a peek and see what’s happening for myself, though on looking at the URL you provided I can’t locate the calendar widget … can you point me in the right direction?
Thanks!
