Hi this query has begun by my inquisitiveness to check the url of my latest post in the facebook debugger, but i get a message which i do not really understand but i have tried to fix it using the steps below. original screenshot - http://grab.by/yPb4

1. so i get my facebook id, here is that screenshot - http://grab.by/yPa2

2. i put the id in the space provided in the SEO all in one social meta, here is the screenshot - http://grab.by/yP9Q

3. i go to Facebook "Open Graph Object Debugger" and i checked url for my latest post but get this error message, here is another screenshot - http://grab.by/yP9g

i don't understand why it is giving me an error message when i have completed the correct instructions as far as i know. Too be honest i'm not really sure what the purpose of putting this ID in the SEO all in one section of social meta does. How will have these error messages affect my wordpress site?
