I can't get my calender to allow me to add events.
I've tried turning my calender on in iCloud and then turning it off but the plus symbol to add an event in the calender app stays gray and I cannot add anything. I've also tried completely closing all my apps, clearing history and cookies, and turning my phone off and back on again. Nothing is fixing this issue. Can someone please help me??? I don't know if this has anything to do with it but I don't use iCloud... At all. I don't like it so I don't even have iCloud turned on.
iPhone 4S, iOS 7.0.4
