Thanks for your quick replies and your tremendous Support.

I disabled the widget kit lightbox and this had no Effekt.

Yes, please try to disable the slitslider, maybe here is the script conflict.
Anyway we have replaced the slitslider with roksprocket slideshow, because its better for mobile devices.

OK.. so now I am confused... I disabled SlitSlider ... Nothing changed.

Then I enabled the Widget Kid Lightbox again ... Nothing changed

and now i am completly confused... should i download the rocksprocket komponent?

Please check if your files exists in:
- warp:vendor/uikit/js/components/tooltip.js
- warp:vendor/uikit/js/components/lightbox.js

if not, please update the Warp

That worked. After having updated the Framework now my SlitSlider works fine and the Pop up works aswell. Good work. Thumbs up!
