Paid configuration is something we're considering, but we're simply too small to do it right now. We'd like to grow in that direction one day. However, we'd prefer to just make our configuration guides and extension easy enough for anyone to use
As for your issue, the error message is indicating that the object you defined is incorrect. Can you go into the Objects area of Open Graph and make sure you set the "type" correctly? From the image, it looks like it's blank (I just see the namespace).
Hope that helps, but if not, let us know,
Alex
