2.3.15 problems with joomla 4

I made a quickreply but it seems that was lost. so i try to reply on this way.

I undo the changes and deactivated the modul "Slider CK Params". Must be some of the old moduls. I use your slideshow since years but after my upgrade to yoomla 4 i did not get it to run..

Now i can create slideshows the problem was in the module "Slideshow CK - Virtuemar"

But somehow the slideshow is still not shown in the page. I tried to change the configurtations but no matter what i choose it is nothing displayed...

Please give me the url of the page so that I can check why it does not show on frontend

I have no idea why but this morning they worked. Maybe I have had a caching problem yesterday. i am really happy thanks for all your help
