Error messages

From time to time. It happens that, even though, the values are given, they aren’t transferred to facebook.

E.g.: https://www.facebook.com/tonguesofdestructionde/posts/1463117823774232

This is what happens sometimes. Title, description, picture etc. are missing in the facebook page but are available in the SEO data fields for the article. And it’s not the first time.

The page I need help with: [log in to see the link]
