WordPress HTTPS with Cloudflare Flexible

I have a site that I converted to https using Cloudflare's "Flexible" SSL. Meaning that I get the benefits of showing https / secure to user, without purchasing an SSL (user to Cloudflare is secure, cloudflare to my server not).

I set up a page rule that automatically forces https. No problems. I installed WordPress under a directory and finding that there are mixed content errors all over the place. First of all, nothing works on the WordPress install because of mixed content. So I temporarily disabled the rule to install WordPress.

Now, if I change siteurl and home in the wp_options table in the WordPress db to https, and enable my force https rul, /wp-admin gets stuck in an infinite loop and won't let me do anything.

What am I doing wrong? All I have is to have WordPress over https with the rest of my site.

You should really use SSL throughout the whole request. If you don't want to go the self-signed route, you can use CF's free Origin Certificate.

WordPress isn't realizing that the request is made via HTTPS from the client because the request from CF to you is HTTP only.

Cloudflare does provide an extra header, X-Forwarded-Proto which will be set to https if the request is running via HTTPS. You could just add

if(array_key_exists("HTTP_X_FORWARDED_PROTO", $_SERVER) && $_SERVER["HTTP_X_FORWARDED_PROTO"] == "https") {
        $_SERVER["HTTPS"] = "on";
}

to your wp-config.php to inform WP that this request should be treated as if it was coming in via HTTPS.

If you prefer to use a plugin, Cloudflare Flexible SSL takes care of that. The Cloudflare plugin by Cloudflare itself also takes care of that, and more (cache purging, change CF settings from WP, WAF).
