Hi Cloudways Team,

I'm experiencing a very frustrating caching issue with my WordPress website: https://biografieblick.de/.

The strange part is that I'm not using Cloudflare at all, but the website still randomly serves broken pages. Sometimes the layout breaks, CSS does not load correctly, fonts become oversized, or the page appears partially unstyled. After clearing the cache, the website works normally again, but the issue eventually returns.

This makes me believe there is a problem with one of the server-side caching layers such as Varnish, Redis, Object Cache, or another cache mechanism.

What I've noticed:

Website randomly breaks without making any changes.
Purging the cache fixes the problem temporarily.
The issue comes back after some time.
No Cloudflare is connected to this website.
This creates a poor experience for visitors because they may see a broken website before I notice it.

I've also seen other Cloudways users report similar issues involving broken layouts that are temporarily fixed by clearing cache, so it doesn't appear to be an isolated case.

I would really appreciate it if Cloudways could:

Investigate the root cause of these recurring cache issues.
Improve automatic cache invalidation.
Provide better debugging tools to identify which cache layer is serving outdated files.
Add logging so users can see whether Varnish, Object Cache, Redis, or another layer is causing the issue.

A managed hosting platform should not require users to manually purge caches whenever the website randomly becomes broken.

Has anyone else experienced this? Any suggestions or a permanent solution would be greatly appreciated.

Thank you.
