Facebook changed the API, sometime around the end of October I think, and a few of my apps that post stuff to Facebook stopped working.
Now I'm trying to fix them up to use the new API, and am looking for some good sample code. I remember this was the problem when I first did the work, I think it was back in 2014.
There are two problems I want to fix this morning.
If you have any help to offer, please post a comment below.
