## 説明

[Click For Full Implementation Guide](https://icwp.io/6z).

Using CloudFlare® Flexible SSL on WordPress isn’t as simple as just turning it on.

This plugin forms an **integral part** to enabling Flexible SSL on WordPress and
prevents infinite redirect loops when loading WordPress sites under Cloudflare’s
Flexible SSL system.

_Cloudflare is a registered trademark of Cloudflare, Inc._

Remember: This plugin is just part of the installation process for Flexible SSL.
[Please follow the full guide](https://icwp.io/6z)

## インストール

For full installation instructions, please review the following article: [Installation Instructions](https://icwp.io/6z).

= 1.3.1

UPDATED: Adjusting plugin naming for Trademark woes.

#### 1.3.0

UPDATED: Update supported WordPress version to 5.1.
 CHANGED: Code adjustments to
only process Flexible SSL in the case where it’s not already SSL.

#### 1.2.2

UPDATED: Supported WordPress Version to v4.5

## FAQ

### Does this plugin affect non-SSL traffic?

No. It only comes into play when Cloudflare is serving HTTPS traffic from your site.

### Should I change my WordPress Site URL to HTTPS?

No – there is no need. Use Cloudflare’s pages rules to redirect your visitors. You
can then safely turn off SSL whenever you want from within Cloudflare and your WordPress
site will still load on HTTP.

### What happens if I disable this plugin AFTER enabling Flexible SSL on Cloudflare?

Your WordPress site will not load on HTTPS/SSL. You will create an infinite loop
loading problem and the only way to solve this is to turn off SSL redirects within
Cloudflare.

### Does I need this plugin if I use Cloudflare FULL or Strict SSL?

No. It is designed only to assist with Flexible SSL.

First time I am leaving a wordpress plugin review after my 10+ years experience 
using wordpress. For some reason, I cannot activate SSL on my own server and cannot
use "Full" SSL setting at cloudflare. This plugin solved my problem nicely.

I dont really understand the problem, because it should redirect loop the whole 
time, but it doesnt, only on some parts in backend and some problems with plugins.
But anyway, this plugin is the solution, CRAZY? and for free. Respekt. Thank you
very much! You saved my life!

i do not really know why. i just wanted to move my site from webspace a to webspace
b. so i did that, changed the IPs in DNS settings of cloudflare and voila i was 
suddenly trapped in an infinite redirection loop. for some reason my webspace b 
provider does not allow me to acitvate ssl on the domain. i stumpled upon this plugin
which seems to fix my issue. so thank you! but i have to admit i still do not understand
whats going on 😉
