is not that easy…
Facebook changed the rules for automated publishing. Now publishing to the timeline is not possible anymore. Instead WP can publish to a page by means of Jetpack. But during configuration of the connection Jetpack shows an error message:
“This connection may not be working correctly”
I re-configured the Publicize connections in Jetpack multiple times. The error message re-appeared after some time again. Then I removed the connection and set it up again. Still the same behavior. But after some minutes of further try and error the error message did not show up.
As a test in published this post and facebook showed it on by extra page. It is still not perfect, because the title of the post is omitted.
