Quick summary
A production debugging note about a page that looked correct locally but kept showing stale output on the live domain.
The problem
The local and expected output were correct, but the live site kept serving an older version after normal browser refreshes and theme-level cache clearing.
What I checked
- Local output compared with live output
- Browser cache behavior
- Plugin cache settings
- Server-side cache layer
- Response headers that hinted at upstream cache behavior
What I changed
- Confirmed the theme/code output was not the source of the stale display
- Cleared the cache layers that were available from the site
- Identified the hosting cache as the likely remaining layer
- Retested after the upstream cache refreshed
Result
The issue was narrowed from a theme or code bug to a live hosting cache problem, which kept the fix path from drifting into unnecessary template edits.
What I'd watch next
- Whether the host cache needs a clearer purge process
- Whether future changes should be checked in an uncached preview path
- Whether CDN or proxy rules are also involved
