About this section

Start with impact and scope

Initial triage
Question	Why it matters
Who is affected?	Public visitors, logged-in users, staff or one account
What is failing?	One page, forms, checkout, admin, email or the whole site
When did it start?	Connects the failure to a release, deployment or external incident
Is data still changing?	Determines whether restoration could overwrite orders or edits
Is there a security signal?	May require containment rather than ordinary debugging
Can the business recover?	Confirms backup, hosting and account access before changes

Use the simplest evidence first

Exact error text and HTTP status
Screenshots with sensitive information removed
Recent update/deployment and audit history
Browser console and network errors for front-end failures
PHP/server logs and WordPress Recovery Mode information
Site Health and scheduled-action queues where relevant
Provider status pages for hosting, email, payments or APIs

Isolate layers safely

Reproduce on staging where possible. Test cache/CDN, browser, theme, plugins, WordPress core, PHP/database and external services in a planned order. Change one variable at a time and record the result. Use a default theme or plugin deactivation only on a copy or within a controlled maintenance window when the impact is understood.

Do not expose debugging data

WordPress debugging can log valuable information, but detailed errors should not be displayed publicly. Enable logging briefly in a controlled environment, protect the log and remove or disable debugging when the investigation ends. Logs may contain paths, requests or personal data.

Choose repair, rollback or restore

A small configuration error may be repaired directly. A failed deployment may be rolled back through version control or a known package. A damaged database or widespread file change may justify restoration. Before restoring, decide how to preserve data created since the recovery point.

Verify the business journey

Public pages and navigation
Login and password recovery
Forms and email delivery
Checkout, bookings, webhooks and refunds
Scheduled actions and integrations
Mobile, accessibility and cache behaviour
Logs and monitoring after the fix

Use the detailed troubleshooting guides

The common-errors guide maps visible symptoms to safe first checks. The step-by-step troubleshooting guide provides an investigation sequence. Migration and Multisite have separate guidance because their failure modes and rollback requirements are broader.

Troubleshooting discipline

Set a stopping rule before investigation. For example, stop live changes after two failed reversible tests, when data integrity becomes uncertain or when security indicators appear. At that point preserve evidence and escalate rather than continuing to experiment.

After repair, convert the incident into prevention: monitoring, an update-policy change, a removed dependency, better staging or clearer ownership. Otherwise the same failure often returns.

Practical next step

Open a troubleshooting record with the exact failure, first occurrence, affected users, recent changes and current recovery options before making another live change.
