Here: ISP Site --> Basis --> Space MB: 50MB (ISPConfig counter?)
the storage space for all users can be set. Right? This usage of it has no effect to the system quote for the webuser managed here:
ISP Site --> User & Email --> WebSpace MB: 60MB (usage of system quota)
Thats all correct and fine. The used space is not from a user of this site as I explained above.
We have the site /var/www/web1/ with the user web1_test. The quota of the site is 10 MB.
Now we upload a 5 MB file with FTP as user web1_test and the website statistic will show 5 MB used space and the used quota is 5 MB too. Now you login as root user (root is not a member of this site) and copy a file with 100 MB size on the shell into the directory /var/www/web1/.
The website statistics will show now 105 MB used space for the directory /var/www/web1/, but the quota which is used by the users of the site is still just 5 MB.
