This extension is for users of SocialPilot.io. It doesn't work unless you have an account. Looks like some people don't understand that. I actually works really well for me.

No instructions provided on how to get it working.

Sadly the app has a bug that adds the following text to any Wordpress site you are the admin of. It happens when you are trying to edit the page. I have sent it in to SocialPilot but they can't seem to understand the basic error.
