So my host (Site5) sells SSL, but not included. I set up cloudflare and that seemed to work. Trying to add cloudflare to subdomain and I got totally lost and temporarily lost my subdomain site. After much frustration I found this:
Don’t know why it didn’t come up on my very first search.
So now I know how, but while trying to get it to work I managed to lose my main domain site. Subdomain working fine . . . I think, but primary says it’s under construction (it’s not). I think the problem is with Site5 so trying to get response from them.
Bottom line: the video is detailed and answered all my original questions, Site5 support has deteriorated substantially over the time I’ve been with them, sigh.
