    Just ran the update on an existing site and it broke it with the fatal errors described in other posts.

    Uninstalled and reinstalled the latest version via WP back end, and on activation I get this message: The plugin does not have a valid header.

    Oh, the site in question is on SiteGround, as I see others have had issues.
