Rename full hostname

[Ilya Sarzhanov]

How can I change the full hostname ?
After the first login, I forgot to rename the full hostname and left "server.example.com", after the expiry of the session is not possible to go to a Panel. How do I change the hostname in the Plesk panel?
Plesk panel 9
OS: linux cent_OS
Thnx.

Is there any update on this ?

I have the same issue, It seems that the "Full hostname *" cannot be changed after it has been set initially. Where is this stored in the server ?
