Thanks for your response.
I have build a new homepage and the problem is fixed.
Thanks again
Kind regards

Hi Yigit,
Thanks for your respons, your right. Last year we probably added a gallery below the slider because the slieder was’nt working, due to the, as we now know, conflicting jQuery updater plug in.
As I remive the gallery now, the slider works correctly and I don’t have double images.
In other words: Solved.
Thanks
Kind regards

Peter

Hi Jordan,

Thanks for the quick respons.
Yesterday I deactivated the jQuery Updater plug in and the sliders do function again, but on some pages there is a double slider visible.
