I read about this and wanted to try Cloudflare out but it will not let me add my blog. It says invalid domain, but I have no idea what that means in terms of a blog that has been around for years and has hundreds of posts.
Hi perilousdreamer,
My suggestion :
You dont manage blog server. You’ve no right on it if its on specific website for blogs (like "makeyourblog.com…i don’t want to advertise) so i think it’s normal you’ve been ejected …
Question is : what do you expect from Cloudflare ?
Can you let us know exactly what you are putting in the site box when you get the error? Make sure you don’t include the protocol (http or https) or www.
Yes, you need a domain name like example.com to use Cloudflare. You can’t use a subdomain of another service like blogspot unless you own blogspot.com.
