Hosting & Performance
WWW and Non-WWW Show Different Websites
The root domain and www hostname display different content, certificates or redirect behaviour. The two hostnames may point to different origins or lack one consistent canonical redirect.
If you searched for www and non-www mismatch, you probably need a safe next step rather than another list of guesses. The root domain and www hostname display different content, certificates or redirect behaviour.
Domain, DNS, hosting, TLS and email are separate systems that meet at public records. A change can look complete from one network while caches or an overlooked record still direct other visitors elsewhere.
What the symptom tells you
The two hostnames may point to different origins or lack one consistent canonical redirect.
The useful question is not “which tool should I install?” but “where does the first confirmed failure occur?” Keep the original state available long enough to answer that question.
Checks to make in order
- Record the authoritative nameservers and current DNS records before changing them.
- Check the response from more than one network and resolver, including the exact hostname involved.
- Keep the previous service available until web, email, TLS and scheduled tasks are verified.
- Issue-specific action: Choose the preferred hostname, configure both DNS records and TLS coverage, then apply one server-side permanent redirect.
How to verify the result
Repeat the original journey using a fresh session and a representative device or account. Check the expected result, nearby functions and any logs or messages that should accompany success. Record what changed so a later incident does not require the same discovery work.
Before closing the task, confirm who owns the system, where the relevant configuration is documented and what monitoring would reveal a recurrence. That small handover step turns a one-time repair into a more dependable operating practice.
A shortcut to avoid
Do not rely only on canonical tags while visitors can browse both versions.
When specialist help is sensible
Ask for hosting help when redirects are split across CDN, proxy and application layers.
