title: Activate plugin on fresh wordpress installation always forcing https on localhost
body: <p>Every time I try to activate a plugin in a fresh localhost WordPress installation, the link is forced to use <code>https</code>. No other links in the fresh install are doing this.  I have checked the SITE_URL and database settings and none included <code>https</code>. </p>
  
  <p>I have reinstalled MAMP and have no other plugins installed.  It's a fresh base installation of WordPress.  I'm using Mac OS El Capitain.</p>
  
  <p>I also checked and all the links to the activate plugin buttons in the source code are <code>http://localhost/</code>.</p>
  
  <p>What else could be causing this?  How can I find the culprit?</p>
