Suddenly cant share our posts to Facebook

Our only site with Newspaper template http://www.elocuent.com is suffering from this issue starting octobre. whenever we/or users try to share to Facebook (and some other mor obscure systems like Flipboard) we either get errors (from share buttons or apps) or only see the link published as text (no extre metadata such as image or text)

All other sites with other themes and same plugins in the same server are working properly (just made sure it was theme related)

We disabled all plugins an still same

Until early octobre everything was working well.

Experiment with this recent link http://www.elocuent.com/habla-humano-46-discapacidad-emprendimiento/

Tried the Objet debug with one random link https://developers.facebook.com/tools/debug/og/object/

We get this eror (sorry in spanish fro facebook) : “El objeto en el URL ‘http://www.elocuent.com/habla-humano-46-discapacidad-emprendimiento/’ del tipo ‘article’ no es válido, porque el valor dado ‘305346456202017’ para la propiedad ‘fb:admins’ no se puede analizar como tipo ‘fbid’.” not valid because cant be analized as fbid type

Whne triying the overall sharing debugger https://developers.facebook.com/tools/debug/sharing/ with same link, the FB system crashes (shows withe page result)

Can someone help with this?

UPDATE: Followinf previous advice from developers in the site we deactivated Ypast FB admin, and still the problem persists (no share posible or only shares links as text without image or text).

When using the tester https://developers.facebook.com/tools/debug/og/object/

we get this error “Warnings That Should Be Fixed
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.”

But is seems to scrape text and image all right. But still no way to share

Thanks

Second update. Some older post work perfectly, some recent don’t

This does not work http://www.elocuent.com/habla-humano-46-discapacidad-emprendimiento/

This works : http://www.elocuent.com/formacion-de-portavoces/

A. We were using and still use SEO Yoast

B. Jus recchecked those instructions step by step and comply with them

B1. SEO YOAST installed and correctly activated
b2. Image bigger than 200×200
b3. as you can see (mentioned already previously) FB debug from instructions not working for some recent items like http://www.elocuent.com/10-errores-twitter-community-managers-afectaron-la-reputacion-empresas

(BTW, the link in your instructions go to different debugger https://developers.facebook.com/tools/debug/sharing/ than the one shown in screengrab)

FB Object debug (the one shown in screengrab in instructions) ( https://developers.facebook.com/tools/debug/og/object/) shows this results (using fetc scrape ….)
”
Warnings That Should Be Fixed
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.
Share App ID Missing The ‘fb:app_id’ property should be explicitly provided, 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.
”

FB sharing debugger (https://developers.facebook.com/tools/debug/sharing/) does not show results (blank page) for links to site using Newspaper theme

But still no share of links

Regards

UPDATE. Editing post and adding manually title, description and image to SEO post in Yoast seo space allows share aganin. (did it manually for post http://www.elocuent.com/lincoln-y-gettysburg-un-discurso-de-la-palabra-por-la-palabra-y-para-la-palabra/ and now shares normally).

Yoast SEO updated 2 weeks ago when this issue started appearing. Now version 3.8

Apparently we need new instructions for YOAST SEO setup or compatibiliuty with theme in order to work….

Acter adding that data manually ( not working for all other posts that rely on YOAST) now FB debugger works
