Social plugin error

When i try to recommend one of my products on Facebook is giving me an error. The post gets posted on Facebook but without the image . Image attached.

Your facebook app id is wrong. Please follow that tutorial:

Ok so now i created the app and got the app ID number, so i put it on the plugin and still gives me that error!

If facebook says that the number is not correct it's because it is...Could you try to check with them maybe ?
