Since version 4.4:
PHP Notice: force_ssl_login is <strong>deprecated</strong> since version 4.4! Use force_ssl_admin() instead. in /var/www/choiceomg.com/wp-includes/functions.php
I am working on a way to spead up the site while retaining HTTPS and will share my findings. Hopefully this means that the new 4.4 does what we all want.
I have been using it with memcached and APC as well as W3TC so my site is not tool slow. I’ll post my results when I’m done.
