 * I’ve seen that error when the WordPress Automatic Upgrade plugin is installed.
   If that is the case, deactivate and DELETE that plugin, because you don’t need
   it at 2.7.

 * Thanks so much, Michael. The problem has been resolved. I deactivated and deinstalled
   WP Automatic Upgrade plugin.
