Cannot select date on date picker

[[email protected]]

Whenever I try to add a featured item or a special item I cannot select a start date or end date. All the dates are displayed correctly but I am not able to select anything.

Note: The date picker for adding new products is working correctly. Only the picker for featured and specials is broken.
Please help.

I just found out that everything works fine in internet explorer 10 but not firefox or chrome
