Slider doesn't work

I just installed your slider and wanted to test how it works, I haven’t changed any of the default settings. I just chose the posts I want to display. The photos are not sliding, there is no next or previous arrow and the pager is also not displayed.

I cannot provide a link because I don’t want to leave the slider this way so here is the screenshot provided.

this is the website it should be published https://www.mybodyartist.de/dein-weg-zum-traumbody.html

Thank you, I really hope you can help me solving this.
