Slider does not appear in front-end, but appears in admin

Hi,
thanks for a cool responsive plugin!

I experience a problem:
the slider does not appear under the page numbers when viewing on the front-end, but when I test in the admin, I do see the slider.

Also, when testing with the iPhone, I cannot scroll the pages…

Here`s an example:

What could cause the problem?

Thank you,
