Hi jimmargraphics, I’d be glad to help.
In the WordPress dashboard, navigate to Settings, then click Drag and Drop Shortcodes. If you don’t see this, make sure you install the plugin for Drag and Drop first.
Once in the settings for Drag and Drop shortcodes, you’ll see 2 options toward the bottom: one for activating FontAwesome Icons, one for activating WebHostingHubGlyphs. I activated both, but I think their template icons are coming from activating WebHostingHubGlyphs. Hope that helps.
