The follwoing is a notification from WordPress.:
We wanted to update you about an upcoming change Facebook is introducing to their platform, and which affects how you may share posts from your website to your Facebook account.
Starting August 1, 2018, third-party tools can no longer share posts automatically to Facebook Profiles. This includes Publicize, the WordPress.com tool that connects your site to major social media platforms (like Twitter, LinkedIn, and Facebook).
Will this affect your ability to share content on Facebook? It depends. If you’ve connected a Facebook Profile to your site, then yes: Publicize will no longer be able to share your posts to Facebook. On the other hand, nothing will change if you keep a Facebook Page connected to your site — all your content should still appear directly on Facebook via Publicize. (Not sure what the difference is between a Page and a Profile? Here’s Facebook’s explanation.) You can review and change your social sharing settings by heading to My Site(s) → Sharing on WordPress.com.
If you’ve previously connected a Facebook Profile to your WordPress.com site and still want your Facebook followers to see your posts, you have two options. First, you could go the manual route: once you publish a new post, copy its URL and share the link in a new Facebook post. The other option is to convert your Facebook Profile to a Page. This might not be the right solution for everyone, but it’s something to consider if your website focuses on your business, organization, or brand.
While Facebook says it is introducing this change to improve their platform and prevent the misuse of personal profiles, we believe that eliminating cross-posting from WordPress is another step back in Facebook’s support of the open web, especially since it affects people’s ability to interact with their network (unless they’re willing to pay for visibility) We know that this might cause a disruption in the way you and your Facebook followers interact, and if you’d like to share your concerns with Facebook, we urge you to head to their Help Community to speak out.
Love The WordPress.com Team
