Account exists but is not active yet
Login or OAuth found an account for this email that is not fully active yet (pending email verification or inactive status). Catalog string; live UI may use related “check your email” / “account inactive” wording.
Why this happens
Registration requires verify, or an admin set status away from OK. OAuth may match the email and refuse sign-in until the account is active.
Diagnose and fix
1. Member: open the verification email, or request a new verification link.
2. Admin: Users → edit → set status OK / activate; resend verification if needed.
3. Confirm registration/approval settings are intentional.
4. Distinct from Account not found (no row) and banned-account emails.
