Following an API update from Instagram (effective June 1, 2016), plugins for integrating Instagram posts on WordPress sites will not work properly unless they are updated. The plugin we’re using on the websites we build, “Instagram Feed” by SmashBalloon, was updated on May 12 and then again on June 1.
This video shows how you can correct your site if your Instagram posts are not showing correctly with this plugin after the June 1 update.
