Are you getting the error “Jetpack: [auth_failed] Authorization header was malformed.” when using the Publicize feature to link your WordPress website. Here is the recommended procedure to fix and or troubleshoot the problem.

How to Fix: Jetpack [auth_failed] Authorization Error

Recently (I believe it’s been since the WP 4.0 upgrade), my Jetpack Publicize settings got deactivated and I had to ‘reauthorize my connections’. What I found is that after the WordPress 4.0 upgrade, you need to follow these steps to fix the Jetpack Authorization header was malformed error.


Get this error on the Publicize account page with every account after the update to 4.7.1. Deactivate/activate plugin doesn’t work. Viewing 4 replies – 1 through 4 (of 4 total) (Maybe) it’s gone after the reactivation after all. I’ll keep an eye on it.
