Can't add any events to my Calendar on my iPhone 5S
All of a sudden I can't add any events to my Calendar on my iPhone 5S. It worked fine just a couple days ago. I haven't loaded any new software and I haven't changed anything in the Settings regarding the Calendar. I have the latest (newest) software 8.2 upgrade. I've done everything I can think of, including turning it off and restarting it. I have not reset it back to factory defaults, I hope not to have to do that.
