slider do not work properly

I had a similar problem with a not upshowing flexslider (it list elements were display:none) and was able to trace it back to the activello/assets/js/functions.min.js script.

Aside that $( window ).load(function() { being deprecated in jQuery 3, it didn’t always seem to trigger on my site. Therefore, I simply removed it.

You could have the same Problem.

This is now the part with the Slider functions which is working for me:

// Slider functions
// Can also be used with $(document).ready()
jQuery(document).ready(function($) {
    if (0 !== $('.flexslider').length) {
        $('.flexslider').flexslider({
            animation: 'fade',
            easing: 'swing',
            direction: 'horizontal',
            reverse: false,
            animationLoop: true,
            smoothHeight: true,
            startAt: 0,
            slideshow: true,
            slideshowSpeed: 7000,
            animationSpeed: 600,
            initDelay: 0,
            randomize: false,
            fadeFirstSlide: true,
            pauseOnAction: true,
            pauseOnHover: false,
            pauseInvisible: true,
            useCSS: true,
            touch: true,
            directionNav: true,
            prevText: '',
            nextText: ''

        });
    }
});
