Has anything been changed recently ?

Did you just install the JCarousel plugin ?
If so uninstall the plugin

This plugin is not new. I have been using it for a long time. It is about 6-7 months. is there another way? except to remove

I assume you tried restarting the webserver ?

If still a problem and you dont want to try uninstall and reinstall the pluign
Then try you could try and contact the developer for help

Issue is not related to nopCommerce itself, but it`s related to third party component, so you should contact with vendor directly.

Regards,

I will remove this plugin and try again.

i tried plugin. problem is solved. Thanks for your help :)

I was curious because I have the same plugin.  Line 81 deals with the "animationSpeedString" setting for a particular carousel, so if you try again make sure it is set to either slow or fast and see what happens.

yours was erroring out on the switch statement:

    var loopItems = carousel.Settings.JCarouselEntitySettings.LoopItems;
    var numberOfItemsToShow = carousel.Settings.JCarouselEntitySettings.NumberOfVisibleItems < 1 ? 1 : carousel.Settings.JCarouselEntitySettings.NumberOfVisibleItems;
    var numOfSlidesToScroll = carousel.Settings.JCarouselEntitySettings.ScrollItems;
    var navigationDots = carousel.Settings.JCarouselEntitySettings.NavigationDots;
    var animationSpeedString = carousel.Settings.JCarouselEntitySettings.AnimationSpeed;
    var animationSpeed = 0;
    var autoscrollTimeout = carousel.Settings.JCarouselEntitySettings.Autoscroll;
    var autoscroll = autoscrollTimeout > 0;
    var navigationArrows = carousel.Settings.JCarouselEntitySettings.NavigationArrows;
    var initialSlide = carousel.Settings.JCarouselEntitySettings.StartIndex - 1;
    var pauseOnHover = carousel.Settings.JCarouselEntitySettings.AutoscrollHoverPause;
    var prevArrowHtml = "<button type=\"button\" data-role=\"none\" class=\"slick-prev\" aria-label=\"Previous\" tabindex=\"0\" role=\"button\">" + T("SevenSpikes.JCarousel.Public.PreviousArrow") + "</button>";
    var nextArrowHtml = "<button type=\"button\" data-role=\"none\" class=\"slick-next\" aria-label=\"Next\" tabindex=\"0\" role=\"button\">" + T("SevenSpikes.JCarousel.Public.NextArrow") + "</button>";
    var carouselArrowsContainer = "#" + carousel.Settings.CarouselHtmlElementId + " " + carousel.NavigationArrowsSelector;

    switch (animationSpeedString)
    {
        case "slow":
            animationSpeed = 300;

            break;
        case "fast":
            animationSpeed = 150;

            break;
    }
