I need to setup different harddisk quota for different website, if i change the quota in websiste, the client is able to change it again. Is it possible do disable this, or hide the quota field in website for the client? I'll attach an image for more comprehension...
When you create the website for the client as admin (instead of letting him create the website), then the client can not change any settings on the first website tab. Another option that might work is to set the quota in the client limits, the client can not set a higher quota then in the websitee, but he would be able to lower the quota move free space between sites when he own more than one site.
