Important: Using a free certificate like Cloudflare's or Let's Encrypt, there are certain combinations of operating systems and browsers that will make your website not viewable and show an error to its visitors.
If your website is from a business or organization we recommend that you hire a paid SSL certificate at Neolo. It is safer and will not generate an error for any visitor.
Step by step to activate a free SSL certificate with Cloudflare:
1. Enter www.cloudflare.com
2. Create a free account
3. Install your domain
4. Change the DNS that Cloudflare tells you to
5. Return to www.cloudflare.com
6. Enter "SSL / TLS"
7. Select Flexible SSL
