Just did the update. Have blank page on both front and back end. I've turned on maximum error reporting through configuration.
On front end receive error:
Fatal error: Call to protected method JApplicationSite::route() from context '' in /u01/www/html/index.php on line 46
On back end receive error:
Fatal error: Call to undefined method PlgUserJoomla::setDefaultEncryption() in /u01/www/html/libraries/joomla/user/helper.php on line 335
