Enter a valid email address
Forgot-password or resend-verification APIs rejected the address as not a valid email (AUTH_INVALID_EMAIL → Enter a valid email address.).
Why this happens
Client/server email schema failed (typo, missing @, spaces, empty). Same locale key can surface on other auth email fields. Distinct from Enter the email address you used to register (empty field on resend panel before submit).
Diagnose and fix
1. Re-enter a normal name@domain address with no spaces.
2. Use the address on the account (registration email), not a username.
3. If the account email was changed by staff, use the current one from Admin → Users.
4. Delivery issues after a valid submit are covered under verification/mail articles.
