How can I change a website's bandwidth and disk usage

It seems that by default, the disk usage for a website is set to 1000 (MB), ditto for the bandwidth usage. Where can I change those values?

Thanks,

Thanks for the info, i did and it’s still showing the default values for my website. What could possibly be the issue?

You’ll have to create a new package with the your desired values.
Then just modify your websites and specify your new package.
This will do the job.
You can’t modify the package “default”
