Linking my website pages to my Facebook page
You can no longer use Website Builder v6 to link new or draft website pages to Facebook. Existing website pages that you've already linked to Facebook are not affected, and you can still update them.
Note: To have those existing website pages display properly on Facebook, your site needs to have an SSL Certificate installed. That's what generates the https at the beginning of a web address. (Learn more about Secure Socket Layer certificates.)
