Instagram feed not showing on homepage

I am using a jQuery plugin called Pongstgrm. After crawling through the set up and code to no avail, I thought it might be a problem with the access ID/token, so I generated a new access token and updated it in the code, however I am getting the following error in the browser console:

Failed to load resource: the server responded with a status of 404 () https://api.instagram.com/v1/users/xxx/media/recent?count=12&access_token=xxx.xxx.xxx&callback=jQueryxxx_xxx

Here’s the code I’m using:

$('#insta').pongstgrm({
  accessId:'00000000000000000000000000000000',
  accessToken:'00000000000000000.00000000000000000000000000000000',
  show: 'recent',
  column: "col-xs-6 col-sm-3 col-md-2 col-lg-2",
  count:12,
  effects: null,
  likes: false,
  comments:false,
  timestamp: false,
  buttontext: ' + '
});

<div id="insta"></div>

I read something about requests to the API not being permitted without the website of origin didn’t own a valid SSL certificate, but I’ve seen so many Worpdress themes use Instagram feeds that I can’t imagine this to be a problem. Any ideas?
