Permission denied while suspending subdomain

[Hardy]

Hi,

I am getting a message of " permission denied " when I try to suspend or disable the subdomain.
Can anyone help me to resolve the issue?
From where can I allow the permission ?

Have you tried repair permissions with Plesk reconfigurator?

Not yet. Let me try and see if it works.
Thanks for your help.
I will update you as soon as I am done.
