Traffic statistic as 0B

[jacko@]

Hello,

Linux Plesk 9.3 - for some reason logging into the plesk control panel and clicking on home and near the top where is displays information about the server, load, disk usage and traffic usage the traffic usage is always at 0B.

"Traffic statistic 0B"

Clicking on domains and listing all domains they have the traffic and disk usage data fine.

Is the Home->Traffic counter not working properly?

Thanks,
jacko
