 * I’m using CloudFlare Flexible SSL function for a long time and I change to Full
   SSL today, the front end seems as normal but when I access wp-login.php it shows
   a blank page.
 * The SSL setting I changed before is Flexible SSL and the URL set as following:
 * Site URL: [http://www.williamtai.moe](http://www.williamtai.moe)
    WordPress Home
   URL: [https://www.williamtai.moe](https://www.williamtai.moe)
 * I used WordPress HTTPS plugin and Rewrite rule to force all link to https connection.
 * Here is the write rule:
 * #Redirect to CloudFlare https
    RewriteEngine on RewriteCond %{HTTP:CF-Visitor}‘”
   scheme”:”http”‘ RewriteRule ^(.*)$ [https://www.williamtai.moe/$1](https://www.williamtai.moe/$1)[
   L]
 * and now I changed the WordPress URL and Rewrite rule setting as following:
    Site
   URL: [https://www.williamtai.moe](https://www.williamtai.moe) WordPress Home 
   URL: [https://www.williamtai.moe](https://www.williamtai.moe)
 * #Redirect for all
    RewriteEngine on RewriteCond %{SERVER_PORT} 80 RewriteRule
   ^(.*)$ [https://www.williamtai.moe/$1](https://www.williamtai.moe/$1) [R,L]
 * Now the front page is okay but the login page serve blank page.

 * Why are you not using https on the site URL too?

 * In Flexible SSL mode the original server is non-SSL, only CloudFlare serve SSL,
   and now I’m using Full SSL that mean both original server and CDN serve SSL, 
   so site URL and WordPress home URL are the same but it cause blank page in wp-
   login.php.

 * The problem cause by CloudFlare official plugin, after deactivated the plugin
   my website back again.
