Sometimes a white space appears under a MetaSlider slideshow.
This can happen if one slide in the slideshow is larger than the others. One solution is adding this CSS to the slideshow. Use this guide on adding CSS to your site.
ul.slides li{max-height: 401px !important;}Occasionally this can also happen if you are using a caching or lazy load plugin. Please try disabling any plugins of that type to see if it resolves the issue.
