Errors in Console
ReferenceError: n2 is not defined
ReferenceError: NextendSmartSliderSimple is not defined
This error can happen, when the jQuery is called in from the footer, and not from the header (probably you are using a custom theme). You should turn on the Async option at the Nextend Settings, that will make our code to wait until the jQuery is loaded, and it will run only after it. If this won't help, check out this.
