Metatag Open Graph facebook ufficiale plug

I just registered to the official forum of wordpress, and I apologize if I have not posted the question well.
I installed the plugin facebook official, I have taken all the steps but all the time when I try to publish the first article via graph api explorer tells me that missing meta tags into the body and therefore I can not post the link.

I just installed the plugin on the blog (wordpress seo Yoast) and this plugin facebook official.

some skilled person knows how I can fix? I thank you in advance
