activate ssh-terminal

[bdoehring]

Hello together,
I would use the SSH terminal in Plesk.
The symbol is grey deposited (apparently not actively)
I dan times under the following point checked:
Server updater- stands a green checkmark and:
SSHTerm - SSH terminal java applet - you have a current version
If I with the pointer of mouse on the symbol of the SSH terminal
show receive I the following Tooltip: "system access must be activated
for the Domain to be able to use around the terminals Client."
Only which I can find far and broad in addition am:
Customer Domain(choice) - authorizations here there are three options:
Customer cannot permit shell access or forbid
customer can the access only on one chrooted to environment permit
customer can access to each type of shell permit

These has I all tried one after the other however the SSH
terminal Button remained further inactive.

How can I activate the SSH terminal?

Thank you already in advance
Bjoern
