Redirect loop with CloudFlare and OpenShift and a WordPress application

I created my WordPress application on OpenShift, and it responds to the URL blog-porta8080.rhcloud.com.

I created 2 aliases on OpenShift

enter image description here

I bought my domain (porta8080.com.br) from a brazilian registrar that don't allow me to add CNAME records without a subdomain like www.

So I created an account on CloudFlare, registred my domain and moved my domain to the CloudFlare DNS servers.

enter image description here

Then I added 2 CNAME records to CloudFlare

enter image description here

I even installed the CloudFlare plugin they say would help me

https://wordpress.org/plugins/cloudflare/

But when I go to http://porta8080.com.br it fails to load the page due to a redirect loop error. I tested on chrome and on Firefox and both throws the same error. Chrome says "ERR_TOO_MANY_REDIRECTS" and inspecting the requests, it gives me several "301 error: Moved Permanently"

enter image description here

The wp-admin page doesn't give me an error. The only thing I can think about is its own .htaccess file.

This is my .htaccess (the one in Openshift is probably without the blog/ parts, I just changed the permalink in both and that's the resulting .htaccess on my machine)

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
</IfModule>

# END WordPress

Got any ideas?

@Edit

There is a problem on my .htaccess for sure. I commented it and put a message on index file and it gets there both by www and without it.

Would you guess why?

This is an interesting issue when you use CloudFlare's Flexible SSL option alongside WordPress. WordPress, in it's core, has an is_ssl function that doesn't account for reverse proxies. Therefore when you redirect to SSL you can get a redirect loop if using Flexible SSL.

The easiest way to fix this is to install Mod_cloudflare on Apache.

Instead, you can add the if statement to your wp-config.php file to resolve this issue:

if (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https') {
    $_SERVER['HTTPS'] = 'on';
}

If you use this method instead of installing Mod_cloudflare ensure that you use the "X-Forwarded-Proto" header instead of SSL for any redirects.
