Thank you for your reply.
I de-activated Ubermenu, created new test page with fully featured slidershow, it is not working.
I created another test page with slideshow without supporting boxes, the slideshow works, but normal menu lists also fall behind the slideshow pictures
Which plugins do you mean by de-activate settings and plugins? If I de-activate WPPAP plugin we will see nothing of the slideshow.
