Facebook Sharing DeBugging: 301 Errors on Facebook Shares

Check to see if you have a plugin installed that is forcing HTTPS. Pressable’s servers automatically force an HTTPS connection and it is unnecessary to use a plugin. In the past the Really Simple SSL plugin has been the cause of this redirect error.

Are you using Cloudflare to manage your DNS? If so, double-check your settings under “SSL/TLS” –> “Edge Certificates”. You want to ensure that the setting for “Always Use HTTPS” is turned off.

Another setting in Cloudflare that could cause this issue in found under SSL/TLS, and then “Edge Certificates”. There is an option for “Automatic HTTPS rewrite” which must be turned off.

If your website is a multisite, you may need to add this snippet to the bottom of your wp-config.php file:

$_SERVER['HTTPS']='on';

If you have a security plugin installed on your site, such as iThemes Security, try disabling it temporarily and test if that resolves the issue. If so there is likely a setting within the plugin that needs adjustment.

Once you have applied one of these fixes to your site you can test the results in the Facebook debugger: https://developers.facebook.com/tools/debug/. Press the “Scrape Again” button to clear the cached scrape of this page.
