Since early January, AdSense publishers have been complaining that they have not received payment in multiple months. In fact, Google confirmed the issue and said they are "taking this issue seriously."
In early February, Google promised those delays will stop and these publishers would get paid at the end of the month, in February. Google said then, "to be noted the holds removed between January 15 and February 15 will be reflected in payments issued at the end of February."
At the end of February, Google seemed to be somewhat frantic in posting help threads to sort out the issues with payments. This should have been a warning sign to many of those publishers who have not seen a payment from Google in months that they may not see a check in the near future.
Yesterday, Google posted a thread at Google AdSense Help saying that many publishers were not paid at the end of February and promises, yet again, to pay publishers, but this time, it won't be until the end of March. Why the delay, yet again? Well, it seems like Google wasn't able to manually remove the "hold" flag on these accounts by the February 15th deadline. So because of that, publishers have to go without pay yet another month.

If you were one of the publishers who ended up with your AdSense account on hold for payments due to an AdSense bug, you were reassured that payments would be processed to be included at the end of February. Originally, the payments were to be included in the payments at the end of February. However, because Google had to remove these holds manually, it seems as though this wasn’t done until after the February 15th cut off time. So what does this mean for affected publishers? You have to wait another month to receive your payment due to Google’s bug, according to AdSensePro Jen.Yes, so now Google’s bug means you have to wait until the end of March for those payments. Still no word on how many publishers are affected or if perhaps some of them made the February 15th cut off so they will get their payments at the end of February as the original post implied, but the new post by AdSensePro Jen seems to say that all affected publishers didn’t have their account’s fixed until after the payment cut off deadline.
All I have to say is that this looks really bad for Google. Some publishers may depend on this income to pay their rent and buy food. If you are one of these publishers, I would try to get on the phone with Google or send them an email to make sure everything is in order for the end of March payment.
