not working at all – [url of post I need thumbnail of video]

I tried on my other sites and it does WORK.

Thing you could take a look:

1. Are you sure the plugin is still activated on your site?
2. Maybe your server disabled CURL so wp_remote_get() doesn’t work?

I think your site doesn’t support CURL or getting content from “other sites” which is common to a lot of webhosts.
Are you on a shared hosting, can we know which hosts you use?

Awesome! Good that you got it sorted out.
FB caches your page for some time so you need to wait a while to try again.

I would then request you change the “1 star” you put, so it wouldn’t confuse other new users of the plugin
