OK now I noticed that there’s a bug in timezone settings.
I live in Germany and when I set my timezone to Berlin the calendar always shows the wrong time 2 hours back (i.e. the event is at 6 am it show 4 am, or the event is on August 16th it shows August 15th – 16th).
I solved this problem by setting my WordPress installation not to timezone Berlin but “UTC +2” time. After this the calender shows everything correctly! But it show the notice that it’s not fully configured yet. It wants me to set the timezone again ?? After doing this (Berlin) everything is wrong again ??
So it would be very nice if you could fix this!
