The bottom line is that I dynamically load or remove elements from the slider using ajax. How after the next request to "restart" the carousel, so that she re-counted the elements?
Everything found the answer: I had a version of jQuery OwlCarousel v1.31 used: $ ("# owl-demo"). data ('owlCarousel'). destroy (); http://www.jq22.com/demo/jquery-lbt20151019/demos/manipulations.html
