Why won’t my site automatically apply updates after upgrade to 3.7?

I found the answer here:

  • If the install uses FTP for updates (and prompts for credentials),
    automatic updates are disabled. (I found this answer which will tell you how to avoid using FTP.)
  • If the install is running as a SVN or
    GIT checkout, automatic updates are disabled
  • If the constants
    DISALLOW_FILE_MODS or AUTOMATIC_UPDATER_DISABLED are defined,
    automatic updates are disabled
  • If the constant WP_AUTO_UPDATE_CORE is
    defined as false, automatic updates are disabled
  • Your WordPress
    install also needs to be able to contact WordPress.org over HTTPS
    connections, so your PHP install also needs OpenSSL installed and
    working
  • Wp-Cron needs to be operational, if for some reason cron
    fails to work for your install, Automatic Updates will also be
    unavailable

This plugin will test these things for you.
