The number of active users, hosts, and teams probably shouldn't be zero.

Indeed. There is a problem with today's stats update.

There were I/O errors (hard disk errors) on the update server.

During the scheduled update it skipped World Community Grid, which disappeared from the combined stats. I now think this was because of the I/O error.

The first fix I ran actually made things worse and it removed all active projects. For some reason PERL/MySQL were behaving very odd and my fix script did not include any active project even though the code was sound.

The second fix is running now. Will take some time. Fingers crossed!

Problem solved. Anybody seeing anything wrong?

That is so much better - Thanks for sorting it and all the good work Willy.
