I had the same problem when I tried to embed a simple Facebook post in an article I was writing.

When I debugged the Facebook sdk.js I saw that the .getVersion returned "undefined" and thus not rendering the widget.

Apparently Facebook can't handle passing query parameters seperated by & instead of & when loading the sdk.js. I had changed my code to & for validation reasons.

Works:        js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.3";
