Instagram authentication is no longer available. Facebook merged Instagram's authentication features and now specifies you need to use Facebook for all authentication purposes.
The blog-looking post you are redirected to is for our Photo Sharing add-on which adds support for Instagram embedded posts (so you can show posts from Instagram easily within your Joomla site) and Pinterest authentication to your site.
I hope that helps explain, but if there's anything else you need, please let us know. Again, we apologize for the severely delayed response.
Thanks,
