Card could not be verified — check your details and try again
Premium card form shows premium.cardForm.verifyFailed when Accept.js (or equivalent) cannot tokenize/verify the entered card details.
Why this happens
Typo in PAN/expiry/CVV, Accept.js error, or client-side validation failure before the charge API runs. Distinct from Card tokenization data is missing (server never received opaque data) and from 3DS authentication failures.
Diagnose and fix
1. Re-enter card number, expiry, and CVV carefully; retry.
2. Hard refresh if Accept.js failed to load (Authorize.net is not available).
3. Try another card or payment method.
4. Admin: confirm public client key / Accept.js config.
