WordPress Site Health can surface REST API issues, loopback failures, HTTPS problems, outdated PHP, background update problems, and scheduled task failures. In an agency handoff, each critical item needs owner, severity, evidence, and a verification step.
Use this when an agency takes over a WordPress site, hands a site to another team, or needs to turn Site Health warnings into a client-safe action plan.
Quick answer
WordPress Site Health Critical Errors for Agency Handoffs should be handled with a narrow evidence-first workflow: record status, group ownership, mark business impact, then verify the result before making broader changes.
What to check first
- Export or record the current Site Health status before making changes.
- Group issues by hosting, WordPress core, plugin, theme, email, cache, and security ownership.
- Mark which items affect revenue, leads, checkout, search visibility, or update safety.
- Collect evidence for each critical item with headers, logs, screenshots, or WP-CLI output.
- Assign the next action and verification test before closing the handoff.
Diagnostic table
Use this table to keep the work practical. It connects the symptom to evidence and a verification step.
| Action | Evidence to collect | How to verify |
|---|---|---|
| Record status | Export or record the current Site Health status before making changes. | Every critical Site Health item has an owner and next action. |
| Group ownership | Group issues by hosting, WordPress core, plugin, theme, email, cache, and security ownership. | Revenue, lead, checkout, and indexing risks are marked separately from housekeeping. |
| Mark business impact | Mark which items affect revenue, leads, checkout, search visibility, or update safety. | Evidence is specific enough for a developer or host to reproduce. |
| Collect evidence | Collect evidence for each critical item with headers, logs, screenshots, or WP-CLI output. | Resolved items include the exact verification result and date. |
Useful command or data shape
Adapt paths, IDs, and privacy handling to the site before running commands or storing data on production.
handoff_item:
issue: REST API unavailable
owner: hosting and WordPress support
evidence: 403 on /wp-json/
impact: editor, forms, plugin updates
next_action: inspect WAF rule
verify: GET /wp-json/ returns 200
Safe fix order
Do the work in a sequence that makes each result easy to prove. Stop if a step produces new evidence that changes the incident scope.
- Record status
- Group ownership
- Mark business impact
- Collect evidence
- Assign verification
Production verification checklist
- Every critical Site Health item has an owner and next action.
- Revenue, lead, checkout, and indexing risks are marked separately from housekeeping.
- Evidence is specific enough for a developer or host to reproduce.
- Resolved items include the exact verification result and date.
Mistakes to avoid
- Do not judge the fix by one browser or the homepage only.
- Do not delete evidence before recording usernames, file paths, timestamps, and response headers.
- Do not add a cache, security, or tracking plugin while the original problem is still unclear.
- Do not leave test users, temporary debug logs, or broad API keys active after verification.
When HandL WP should help
Bring in help when this affects leads, checkout, search visibility, malware risk, paid media reporting, or a client production site. HandL WP can trace the issue through WordPress, hosting, cache, tracking, and Search Console, then verify the workflow after the technical fix.
If this is active on a production site, turn WordPress Site Health errors into an agency handoff.
