After following the Cloudflare SSL tut (How To Use Cloudflare For SSL), I get a “ERR_TOO_MANY_REDIRECTS” in my website (https://iffantaria.cf/). If I turn off the orange cloud in Cloudflare cpanel, website shows up again normally, but with insecure flag. I already have disabled “Always HTTPS” and “HTTPS Rewrites” in Cloudflare cpanel and still the same. All plugins from WP are disabled too. 
Seems fine currently?
Try a new incognito tab on your browser or flush out browsing data.
I follow the solution provided by teodor and it worked! Sorry for posting a solved doubt and thank you for your support 
No worries happy site building
