Facebook error! Need help!

  • I don’t really think you’ll be able to. Facebook is trying to communicate with your site to generate a preview, but you’re blocking Facebook from accessing your site with a password.

    You say “after you disabled the plugin”.

    I believe Facebook caches the Open Graph data (title, image etc) for a period of time. When Password Protected is active, FaceBook cannot access your normal pages so it returns the details of the login page.

    I have read you can force the Facebook Open Graph data cache to clear by entering the URL of the site here:
    https://developers.facebook.com/tools/debug

    If you wanted Facebook to show some useful information when Password Protected is active, you could use the plugin’s password_protected_login_head action hook to output some custom Open Graph meta tags as described here:
