The calendar for a site I manage is skipping Dec. 9 (see http://mother-of-god.org/index.php/calendar-2/?cid=all&month=12&yr=2013).
I've entered an event for that date. I deleted the event to see if it made a difference and I actually lost a couple more days (the 10th and 11th, I think).
What should I do next? Uninstall and reinstall? Would I lose the events I've entered?
