Facebook debugger warnings

When debugging a typical link on our site, I get these warnings:

—-

fb:app_id hasn’t been included in the meta tags. Specify the app ID so that stories shared to Facebook will be properly attributed to the app. Alternatively, app_id can be set in url when open the share dialog. Otherwise, the default app id( 966242223397117 ) will be assigned.

—-

Meta with name instead of property The meta tag on the page was specified with name ‘author’, which matches a configured property of this object type. It will be ignored unless specified with the meta property attribute instead of the meta name attribute.

—-

Please address or explain! Thanks. 🙂

You can set app id for fb with yoast seo, at least that is how i do it.

Thanks! May have to actually start using Yoast…
