Yout plugin is great and works well,but I found some problem about recuring event. I create new event and choose Repeat 'None (run once)' then Save and Close. Recuring Event Pattern still repeat on Daily Every 1 day (FREQ=DAILY;INTERVAL=1;COUNT=1;). How can I resolve it?

FREQ=DAILY;INTERVAL=1;COUNT=1; is equal to one time.

So it is doing what it is supposed to unless you are seeing it appear multiple times on the calendar display page.

OK. I misunderstand myself, lol. Thanks for your reply.
