The first time I noticed “Check Error – State Unknown” I thought it was a payment issues affecting only me, as a Canadian publisher in a US-only program. However, beginning in December when October earnings were being processed, many more YPN publishers noticed this error showing up on their payment reporting screen in the YPN control panel. It would appear a few days before the check was received by the publisher.
I have had a few people ask me about this error this month, and worried about what it might mean for their payments being sent. But it is a good thing to the “Check Error – State Unknown”, and you should expect to see your check shortly. I am not sure if this appears in all accounts, but I haven’t seen any mention in the forums of people not seeing it after it showed up for myself and others this month.
