I purchase the plugin and added my first widget "Woocommerce Product Carousel". But then I added it to my page and it gives me a jQuery error.

Uncaught TypeError: a(...).find(...).andSelf is not a function
    at c.<anonymous> (owl.carousel.min.js?ver=5.4:2)
    at HTMLDivElement.e (jquery.min.js?ver=3.2.1:2)
    at HTMLDivElement.dispatch (jquery.min.js?ver=3.2.1:3)
    at HTMLDivElement.q.handle (jquery.min.js?ver=3.2.1:3)
    at Object.trigger (jquery.min.js?ver=3.2.1:4)
    at HTMLDivElement.<anonymous> (jquery.min.js?ver=3.2.1:4)
    at Function.each (jquery.min.js?ver=3.2.1:2)
    at r.fn.init.each (jquery.min.js?ver=3.2.1:2)
    at r.fn.init.trigger (jquery.min.js?ver=3.2.1:4)
    at e.trigger (owl.carousel.min.js?ver=5.4:1)

What is going wrong? It looks like UE is not compatible with the jQuery version in my theme :(

I just find out that owl-slider is not compatible with jQuery because of the ".andSelf" function (which should be .addBack in jQuery 3.x). For now I altered the widget and put the Slick slider in it. Now it's sliding again. :) 

Great plugin btw!
