Question : There is an ALERT message: " Check Other DNS Records for smithscateringlondon.uk"
Are those records relevant to Email only? I think, emails are pointing to origin server, right?
What does it menas 'DNS only"?
A Cloudflare guide say: " leaving your records as DNS-only means that Cloudflare cannot optimize, cache, and protect requests to your application or provide analytics on those requests"
Usually web sites are “Proxied” so requests pass through Cloudflare first so Cloudflare can protect the site and apply your settings before sending the request to your server/host.
For non-HTTP/S traffic (such as email), DNS records must be “DNS only” since Cloudflare doesn’t proxy that traffic (unless you use Cloudflare Spectrum).
I’m not sure if this is relevant to this question. I activated Cloudflare to improve caching without a plugin, but website testing doesn’t show visible improvements. What should I do next?
Although Cloudflare will speed up what is caches for you, you’ll still need to fix your origin speed so it can serve to Cloudflare faster when called upon.
Read here about what Cloudflare caches by default, you can then change that if you want by using Cache Rules…
You can speed up the redirect from your domain to www by doing that on Cloudflare instead of in Wordpress, see here…
