JenSense reports that AdSense error means many publishers must wait until NEXT payment cycle for August earnings. This is the emails thousands of AdSense publishers received as a notification of the error on Google's part.
Hello, Due to an issue with our payment system, your most recent AdSense payment was mailed to an incorrect address. Our system pulled the payee name and address information from your Google AdWords account, rather than your AdSense account, when printing and mailing your check.
If you are unable to receive your payment at the address listed in your AdWords account, or if the payee name is incorrect,please respond to this email so that we may cancel this check. Your earnings will be credited back into your account and included in your next payment cycle. Once this process is complete, you will see a 'Payment Canceled' line appear on your Payment History page.
If you are able to receive your payment at the alternate address, or if you have already contacted us about this issue, no action is required on your part.
We sincerely apologize for any inconvenience this may cause. Please don't hesitate to contact us with any questions or concerns.
Sincerely, The Google AdSense Team
