Does the Comments Plus plugin no longer work?

I know there have been many changes with facebook lately, but I followed the guides to the T, and still have only the google comment option working on my site. https://www.seahorsewhisperer.com. I'm trying to redo this site, and plugins are supposed to be the EASY way, yet I've spent days now trying to get it working. I'm not even sure what to ask besides whether this is a known error?
