We also just did the update and it responded with a fatal error (white screen on front-end and admin). Was not JetPack, as I can disable GeoDirectory (all) and it comes back. Tried removing JetPack and leaving GeoDirectory installed and still fatal error. Also removed each of the plugins one-by-one, trying with GeoDirectory, but still does not resolve the issue.
Do you know what might be causing the failure?
