After I have updated ISPConfig to from version 3.0.2.2 to 3.0.3, the "Shell" and "Cron" fields in folder "Sites" are disappeared. Is it the bug, or I did something wrong? The upgrade process went without any errors. My server is running under Ubuntu 10.04 TLS
Thats no bug, its a new feature. You see only the fields in the left menu that are enabled for the client. If you see no shell field for example, then the client is set to have no shell users.. Same for cron.
