Instagram feed plugin doesn’t display on my website

If your WordPress site doesn’t display Instagram Feed, first of all you need to check the following:

• There are page areas where WordPress shortcodes don’t work, and you need to make sure that you haven’t added the InstaShow shortcode to such an area. If you did, you need to re-insert the shortcode into an appropriate place, or read our shortcodes article at What are WordPress shortcodes and how do I use them, and find out what you can do to display the feed exactly where you want it to;
• Private Instagram account – if your feed’s source is an Instagram account, it’s got to be public. Instagram API doesn’t allow us to work with private accounts;
• Make sure that there aren’t any JavaScript errors on your website, in your theme and other plugins. If you find any, fix them first, and check that InstaShow works;
• If your WordPress theme is ajax-powered, here’s the information that might help you - Instagram feed InstaShow doesn’t load on ajax-powered WordPress websites
