I had been using the Grid for featured content and decided to switch to the Slider. In the preview when customizing the theme the Slider is displayed and updates when I change settings. When I Save and Publish the Slider is not displayed when viewing the site. I have emptied all caches on the site and my web browser, and viewed on different computers. Switching back to Grid displays featured content properly.
WordPress 3.9 and the Ridizain 1.0.33 theme are all up to date. No child themes in use.
Thanks for your help!
