Feed Excerpts For Divi is a simple plugin for the Divi Theme by Elegant Themes. This plugin provides excerpts for the Blog Post Feed when the Feed is set to show the Summary instead of Full Text.
WordPress filters out shortcodes when it is set to Summary, which leaves the feed content empty for posts using the Divi Builder. This plugin resolves that by generating an excerpt from the first Text Module on the post where the Divi Builder is enabled.
Sample RSS Feed: (http://feeds.feedburner.com/ferventsolutions/feed-excerpts-for-divi)

NOTE: This plugin is not necessary when using Full Text for the Feed
