Actually scratch what I said @arjangriffioen. I have exactly the same issue as you decribe, since updating to WordPress 4.4. Does anyone have the same issue or a fix?
I had the same problem. It was a jquery conflict caused by the page template. I took out the Jquery Library link that the previouse developer put in the page head and wp enqueue scripted it properly as recommended by WordPress.
Thanks for your quick response. It looks like you were right. My theme was using an older version TGMPA so I updated it to the most recent one on it seems to be working fine. Thanks again for your help.
