On a mobile device no reaction on user events

On a smartphone/tablet the slideshow of my website ( www.hugograf.com ) no longer responds to events. It works on Windows operating system, but not on an iPad, iPhone, Android Tablet and Android smartphone. I have made a big upgrade of Joomla, PHP and the templates. Before that it worked well. Even on the 2nd slide(Neuschwanstein Castle) where in the text a link is shown, that does not work.

Hi
please explain me what you mean with "no longer responds to events"
is this a problem by clicking on the prev/next buttons, or something else

Hi
I have produced a 45 second video . This shows how it was and how it is now.

ok, reproduced on my ipad
please try to install the previous version 1.4.26 of the slideshow module (don't uninstall, just install the previous version to downgrade) and tell me if this fixes your problem

Unfortunately, I don't have this version available. Where can I download version 1.4.26? Thank you for your help.

try it here
