Instagram Widget not working

Hi guys,

I was wondering if anyone is experiencing the same issue. I installed the Instagram widget in the footer of my blog. it was all working the first days and although I haven’t changed anything it stopped working while Facebook and Twitter are still displaying. Any idea what the issue could be? It’s really stressing me out now :ambivalence:
Thanks for your help.
