• Recently we’ve picked up a lot of these 3189 errors, stating “The vendor data is invalid”.

    From looking at the detailed error messages in SagePay, I can see the things that connects all these recent errors is that the payer has used a non-alpha-numeric character in their name (such as “David Benton-Smith” or “Dara O’Brian”). These are the only transactions that are failing and returning this error, and this has only started since the last plugin update.

    Is this something happening in the plugin, or something at SagePay’s end?
