Can you assist me with Comments +?

I installed it. I followed the directions for creating apps and plugging in the #s for Facebook and Twitter. But when I go to leave a comment from Facebook, I get a message that says: "Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains."

Even with the guidance I've gotten from staff, I have not been able to figure out any of your themes. I at least wanted to use some WPMU plugins, since I paid for a yearly membership. Hope someone can help. Laymen's terms please. :slight_smile:
