We are dealing with an issue that might impact when we record auction payments (and credit them to the winning bidders). Thus, until that issue is solved, we are going to suspend the ability to pay for niches for the time being.
If you are a winning bidder, you'll be notified when we have resolved the problem and can accept your payment (and you will still have 24 hours from whenever we start accepting payments to send us your payment).
We will provide more details later, but I wanted to let everyone know now, since some of the first auctions are expiring soon.
This issue does not impact the process of selecting a winning bidder at all- just the payment mechanism.
