title: Wordpress admin stuck in https, how to turn it off?
body: <p>The admin side of my wordpress site is stuck in HTTPS and very slow as a result.
  I am trying to set the admin to HTTP.
  Here is my setup and what I've tried so far.</p>
  
  <ul>
  <li>Godaddy VPS with Godaddy SSL certificate</li>
  <li>In wp-config.php  I have: <code>define( 'FORCE_SSL_ADMIN', false );</code></li>
  <li>Tried installing the <a href="https://wordpress.org/support/plugin/wordpress-https" rel="nofollow noreferrer">wordpress-https</a> plugin. The admin https checkbox is greyed out / disabled.
  Here are the settings on that plugin.

  <li>Check httpd.conf and htaccess files for any rewrites - none found.</li>
  <li>Server does have Vernish installed - asked Godaddy support to check for any relevant configs in Varnish. None found.</li>
  <li>I have tried commenting out code in wp-includes/functions.php based on suggestion <a href="https://wordpress.org/support/topic/ssl-enabled-by-default-for-loginadmin-how-to-remove?replies=17" rel="nofollow noreferrer">here</a> (see comment by user joelbair).</li>
  <li>I always flush caches, and sometimes reboot the VPS completely after making changes.</li>
  </ul>
  
  <p>Any suggestions?
  Could it be related to SSL signing certificates or how SSL was installed on the server initially?</p>
