Hello to all,
I have Plesk installed on my local system (7.5.2 on fedora 2) When ever i am trying to create a new doman it will give me following error.

ERROR
Client ID is undefined.
0: /usr/local/psa/admin/htdocs/clients/cl_pref.php3:8 psaerror(string "Client ID is undefined.")

I am not able to understand the error. Please help me on this issue.

Thank You
Mahesh

My problem is get solved. You have give correct directory permission for session directory.
It should like this only then it will work.
drwxrwx--- 2 root psaadm 4096 May 20 09:42 sessions
With this your problem will get solved

-rw-r--r-- 1 psaadm psaadm 29 Feb 14 2006 version
drwxrwx--- 2 root psaadm 4096 Nov 30 05:50 sessions


file permissions are intact.. stil we are getting the below error.
------------------------------
ERROR

0: /usr/local/psa/admin/htdocs/clients/cl_pref.php3:18 psaerror(string "Client ID is undefined.")
------------------------------
any suggession?

I am guessing this is when you try to login to a user? Does this happen for every user or just some or what?
