What’s more frustrating than getting a “404 page not found” error in WordPress when your pretty permalink page, post or custom post type does exist?
Failed to set referrer policy error
Not sure if it was the latest update or not, but I just noticed this error popping up. When I deactivate W3 Total Cache, it goes away. I have tried uninstalling and reinstalling the plugin with same results. I have searched and found no fix, only descriptions of the error.
Me too.
For now in the browser cache tab, check the new additions and uncheck referrer policy.
