suddenly stopped working

I have been using this plugin at http://www.shadyacrespetranch.com to display on the “happy dogs” page and also in the footer widget.

One day pictures stopped showing up. i logged out and logged back in to instagram form the plugin page. I also tried to revoke access form instagram and then reauthorize. nothing ins working.

I ran this command form the api console:
https://api.instagram.com/v1/users/***my user id***

response: HTTP/1.1 200 OK

looks fine. what else cna I try?
