Friend Connect?

If you see to the right my members gadget says this

"We're sorry...

This gadget is configured incorrectly. Webmaster hint: Please ensure that "Friend Connect Settings - Home URL" matches the URL of this site."

Does anyone know what this means and how I can fix my members gadget? Do I need google connect in order to see the members gadget? Looking on google it seems like they are doing away with google connect. Im confused. cans anyone help me?

thanks
