Slideshow disappeared on startpage

Hi,
SlideshowCK worked fine. But suddenly there is on the startpage only a grey block. Adding another menu-item to show, it appears on that side correct.

I have joomla 3.5.1., protostar-template, position 7 at the top of that position.

Website is: Startseite Bürgerbataillon Neesen
On menu "Schützenfeste" it works fine.

Hi
you have some JS errors related to "com_extrawatch" and a "heatmap", you must fix this, which is probably killing the slideshow
CEd

Thank you, that was the solution! The map was the reason (at work I can login but have no possibility to find out). After blocking it the slideshow work fine again. I have to see, how I can put the map on the startpage without related error to slideshow.
