how do I activate iPhone calendar? The sign is grayed out.
I Was having trouble syncing the calendars on my iPhone 5s, with ios9.1. I eventually deleted my calendar with all its data. Now that I reinstalled it, I am unable to add entries since the + sign is grayed out. Also, under Show All Calendars, I only have Facebook birthdays, US Holidays, Birthdays and events found in mail. My iCloud and home calendars are missing. I have checked my settings and everything seems to be in order. i need help!
iPhone 5, iOS 9.1
