I have moved a few domains over to Cloudflare, set SSL for the certificate, and they’re working fine.
However, for two domains, it shows the certificate as R3. This is meaningless to me, and incredibly there is no mention of it at all in the Cloudflare help section.
So, would anyone be so kind as to tell me what is R3, what does it mean, and how can I get the website certificate to properly show as Cloudflare?
Thank you ever so much.
