Baseline checks

• Confirm a supported release and runtime

• Check disk, system time, DNS and TLS

• Verify database connectivity and upload permissions

• Clear caches and test in a private window

• Determine whether every account or one role is affected

Useful support evidence

• Product and version

• OS, runtime, database or WordPress/WooCommerce versions

• Reproduction steps, expected result and actual result

• Timestamp with timezone and error ID

• Relevant log excerpt after removing passwords, tokens, cookies and customer data

When to roll back

Roll back when data integrity is at risk, primary login fails, a migration is incomplete or impact exceeds the maintenance window. Do not continue experimenting against production without a recovery point.
