Shared guide
The Diagnostics tab turns common setup and access risks into actionable checks.

Run the checks
Select Run checks after changing a provider, validation target, cache setup, or access rule. Resolve critical items first, then warnings.
Emergency access
Confirm that a private emergency login link is configured and current before protecting wp-admin and login. Use Manage emergency access to replace or review it.
Environment information
Load Environment and support information when preparing a support request. Review it for sensitive values before sharing.
When all checks pass
If behavior is still unexpected, compare Search results with Validation logs, purge all page caches, and confirm the request reaches WordPress.
