PayPal Payment processor response: Result: 29

I’m using Websites Payments Pro and have noticed a bunch of these failed transactions with this Payment Processor Response:



Payment processor response: Result: 29.



What does this error mean? I checked the PayPal API error code list

[URL=“https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer”]https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer[/URL]/e_howto_api_nvp_errorcodes and don’t see this error listed. Any help would be great!



I’m running Version 2.1.1.
