My Adsense in UK and India is fine. No probs. However, don't panic.. just write to Google and give it sometime. Must be a delay in click reporting with your particular server.
I don't know what happened there but it was a huge concern. But things are back to normal now. However no updates on the day when things went awry. I cannot believe it was no clicks, not with the amount of traffic that particular site gets and it has been doing reasonably well for some time now just goes to show that you cannot depend on one source of income when working online
