vSlider not visible

Hello,

we use joomla 3.6.3 and php 7. I have the module vSlider installed. But it is not visible. An error occurs: "ReferenceError: $hsms is not defined". (see at www.student-mag.de ) What can i do?

regards,
Mathias

If jQuery Easy is disable, the error occurs "src is undefined".
If iquery is loaded in vslide module or not, has no effect

There are also problems with the gzip compression in joomla.
