Date element doesn't show the calendar pop up

Anyone else with the same issue?
I can't see the calendar pop up in date elements (the same problem about the time field).

Maybe aJoomla template issue. Is it showing up in the backend? Did you try Protostar template,

Hi, Troester. Thank you for your answer.
No, it doesn't work in the backend too. I'm using Beez_20 template. It should work, right?
