I’m a user with a free plan, I set up my website that did not have SSL previously, and I installed the Cloudflare SSL, right now I can not access to my original website https://example.com by default goes to this domain https://example/defaultsite accessing to a blank page.
There was just yesterday (yet another ) where a user swore it was not a local thing and guess what it turned out to be eventually So please understand if I am a bit careful in this regard.
But for starters we can begin with your domain, unless it really is example.com, but then that seems to work, doesnt it.
