The screen image has changed, I don’t know why but the bit about “success” has disappeared. I produced a compressed screen image of what is displayed now, but can’t figure out how to post it in my forum reply.
If the other person who replied to this topic is correct in saying free Cloudflare SSL certificates can’t be used for free InfinityFree subdomains, then there’s no point in perusing this topic, but thanks for your interest.
Are you sure about this, and can you give a link to something official which says this? If this is true, how do I remove the self signed certificate which has been added to my domain?
