I am trying to insert a new gallery into an article, and utilize the new slideshow feature built into the latest version of WordPress (i.e. not from an outside plugin). When I go to preview the article, it states “This slideshow requires JavaScript” and all I see is a black bar.
I have the latest version of JavaScript installed on my computer. Is there an additional plugin I need to install to be able to use the Gallery Slideshow feature built into WordPress?
My other guess is maybe the slideshow doesn’t show up for some reason in preview mode?
