Hi Benny,
Did you ever find a solution for this? Currently have a website that needs instagram feeds and I'm a bit a stuck.
Thanks,

Could this be the problem?
Instagram Platform Update
Reminder: Instagram’s platform changes will go into effect for apps created before November 17, 2015 on Wednesday, June 1, 2016. If you have not yet applied for permissions review, please do so here. Apps that have not been approved and were created before November 17, 2015 will go into sandbox mode on June 1, 2016. (http://developers.instagram.com/)
Sorry forgot to reply this but yes ^. I was able to get it working using instafeed (js script independent from modx). However instagram developer accounts now only support one feed per account, and it does require an access token key of the persons account you're trying to grab data from, bummer.
Sorry missed all these replies.
LK yeah did manage to solve and apologies I never posted how i solved it.
BobRay, yeah was related to that although the initial forum post i linked to had a work around but once the 1st kicked in all the links that help generate an access token also stopped working.
I'll report back with exactly how i solved this in case others are having issues.
