Jetpack Carousel doesn't work

Hello,

Could anyone help me finding out why carousel dosn’t work properly for us?

First we used NextGen gallery, and it was fine, but after a while it messed up our site (sliders couldn’t run, and galleries didn’t worked as well). So I deleted NextGen and started to use carousel, but full-screen photos don’t open up, only the black background appears and nothing else.
An example here:

Please suggest any idea what could be wrong.
Thanks
