TB54 When you say "update your CNAME to point to cname.freeflarum.com", you mean "cname" in the url must be replaced by our freeflarum name? Because in my host, the CNAME redirection already points to a "cinstudtest.flarum.com".
Apologies for the confusion. The CNAME now must point to cname.freeflarum.com
instead of your FreeFlarum host, as all *.freeflarum.com
hosts are proxied through Cloudflare
TB54 And what do you mean by resetup the domain?
Set your custom domain to your FreeFlarum host (reset it in the FreeFlarum settings), then update your CNAME record at your registrar, then set your FreeFlarum URL to your custom domain again (technically, "re-setup" it)
