I just tried upgrading my plugin from version 3.1.5 to 4.1.5 and I am having some issues with 404s when trying to load videos.
I have left it installed on my testing site for you to review.
http://riverine.wpen...roducts/videos/
I have tried using POST and GET and it errors either way.
I have disabled all other plugins and left it with debug on for you to look at.
When you click on a thumbnail, I get the following error in my console:
