Epic. And fixing it was going in circles. I'm not sure who wrote the instructions but I've now taken a cultural tour of Failbook's Developer Department and have the start of a migraine.
Do you think they can hire someone there who knows how to write instructions clearly? Google was a snap but their instructions were clear with screenshots.
Failbook is not worth the bother so I quit and removed the plugin. It seems so far every FB plugin I have tried has had the same instruction problems.
