A troubleshooting change is not complete until the original symptom is retested and temporary workarounds are removed.
- Repeat the exact action that failed before the change.
- Test both logged-in and logged-out behavior when relevant.
- Test HTTP and HTTPS plus root and
wwwhostnames when DNS or SSL was involved. - Review logs again to confirm the original error no longer appears.
- Re-enable any security control, cache, plugin, or maintenance setting that was disabled only for diagnosis.
- Remove temporary debug output from public pages and disable verbose debugging on production sites.
If the symptom returns as soon as a component is re-enabled, that component or its interaction with another component remains part of the problem.
