Calendar Problem Message

[AlaAshour]

Kindly I need help with Xperia Z1.

It keeps giving a message saying (Unfortunately, Calendar Storage Stopped Working),

what is wrong with my phone?

Regards

Do you have any taskillers, task managers? antivirus? have you disabled any app? have you blocked any background data from any app?

I used to get this error message once, and the problem was that I had disabled Calendar storage app. Look at Settings--Apps--All--Calendar storage. Otherwise, as uliwooly said above, may be some other app is interfering with the Calendar app.
