For all those who used the great MMM-Instagram; I have created a new module to load Instagram using the updated Facebook API.
It requires a Facebook developer app and the Readme contains the necessary steps to get it up and running.
Hi all, had the same problem, Instagram was acquired by Facebook who have updated the way the API works.
I spent a couple of days writing and testing a new module for Instagram that was based off the original.
It requires a Facebook developer account and app, but I have explained it as best i can in readme
