# SSL error during network upgrade

 * Hope this may help others:
 * On a WordPress 3.8 installation with three sites which is administered over SSL
   only the upgrade to 3.8 went smoothly, but after that the network upgrade failed
   with an SSL error.
 * The solution I found was to temporarily disable
 * `define(‘FORCE_SSL_ADMIN’, true);
 * in wp-config.php, doing the network upgrade over HTTP and enabling HTTPS afterwards
   again.

 * It turned out that there was indeed a small problem with the SSL certificate (
   an intermediate certificate was missing). WordPress seems to check more thoroughly
   than most browsers.

 * I’ve been looking for this line:
    `define(‘FORCE_SSL_ADMIN’, true); Cannot seem
   to find it. Should it be added? If so, where?
