Unable to login after upgrade

[seikan]

I just upgraded Plesk on my Windows 2003 from 8.2 to 8.6. After the update is completed, I'm not able to login to control panel. I'm getting error as belolw:

Unable initialize session:
---------------------- Debug Info -------------------------------
0: plib\cmd_loginup.php:262
createSessionCommon(integer '1', string 'admin', boolean true, boolean false, string '', boolean false)
1: plib\cmd_loginup.php:370
createSessionAdmin(string 'admin', string '********', boolean false, string '', boolean true)
2: plib\cmd_loginup.php:132
createSession(string 'admin', string '********')
3: htdocs\login_up.php3:27


I have referred to the KB at http://kb.odin.com/en/997 but it doesn't help. Any alternative solutions?

Do you really have enough free diskspace there and sessions folder in "%plesk_dir%\admin\ ? We have old bug regarding this problem and fix only that already described in the mentioned KB article. Please double check it.

I have double confirmed that the folder "C:\Program Files\SWsoft\Plesk\admin\sessions" is existed with correspond persmission, and there are 20GB free space on my server hard disk.

Any idea?

 

[IgorG]

Not sure but maybe sessions folder has incorrect permissions? Dir you tried to check it with reconfigurator?

I have ran the Plesk Reconfigurator to check the folder permission on "C:\Program Files\SWsoft\Plesk" but can't find any problems.

I reliazed that when I navigated to "https://<my_ip_address>:8443/login.php3", a session file such as "Session_4f9fcc2da4e56fce1c49e4bdaf7ab289" will be created in "C:\Program Files\SWsoft\Plesk\admin\sessions".
But once I login, the session file is gone, and I get the "Unable initialize session" error on my browser again.

In this case, shall I downgrade my version back to 8.2?

 

[IgorG]

I think that upgrade would be much better than downgrade.

 

[seikan]

I've reinstalled Plesk 8.6, still getting the same issue. Really out of idea now.

Finally, I manged to fix this problem. I downloaded and run the updater from ftp://download1.swsoft.com/Plesk/Au...0/139967/Plesk_8.2_to_8.6_DatabaseUpgrade.exe
