I am unable to add events to my calendar as the + sign is greyed out and all existing events that were there are now not showing..
The information is currently showing on Ipad and in the Cloud.
iPhone 4, iOS 7.1.2
Go under settings. Select Mail, Contacts, Calendars. You must click on individual accounts, and move the slider for calendar to the "on" position. For instance, I have an iCloud account, and multiple gmail accounts listed. I clicked on each account, and turned on all of the calendar sliders.
