cloudflare got a lot of data centers. So while some are showing green right now some will not. The certificate will spread steadily to all locations and most times it takes less then 24 hours. Alas it can take up to 24 hours at most. As long as it shows green tomorrow, and as it seems the website is not "live" I would not worry for now. And with the config change, the website works as well ?
If the problem still persist 20 hours from now tell me in this thread and i will attempt to help you further
