If you use Cloudflare, just set it to “Full” and make sure you also have an SSL certificate on your site in the control panel.
-------Set-up Cloudflare SSL-------
Setting up Cloudflare DNS is quite easy!
- Go to the SSL/TLS section on dash.cloudflare.com
- Click on the “Flexible” Setting (If you want to use the “Full” setting (which is more secure), you need to install an SSL certificate first - Video - KB article )
- That’s it! (If you go to “https://yoursite.com” it will no longer show the unsecured message!)
OPTIONAL: If someone goes to http://yoursite.com , they will not get the lock icon (They will get the unsecured message). So, you want to have everyone that goes to the unsecured version, automatically get redirected to the secure version! It’s easy to set up too!
Using Cloudflare (The easy way)
In the SSL/TLS → Edge Certificates tab, the setting “Always Use HTTPS” is set to On
Now, if someone goes to http://yoursite.com , they will be automatically redirected to https://yoursite.com! It’s totally secure now!
