No 'Always Use HTTPS – On' button with free plan

What setting are you looking for exactly?

If you’re referring to the Page Rule, click “Forwarding” and type in your site URL with https. You should refer to this article: https://www.icontrolwp.com/2014/10/enabling-cloudflares-universal-flexible-ssl-wordpress-without-infinite-redirect-loops/

Thanks.

Thanks for the reply. Cloudflare messed up issuing me my SLL and they had to re-issue it. So the “Always use https” rule was not showing up until they re-issued the SSL. Everything is working now. Thanks.
