• Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Hello,

after backup restore (35 GB data), we can't login to plesk control panel anymore.

After login, we get this error message:

ERROR: PleskException
Unable initialize session:

0: /usr/local/psa/admin/plib/cmd_loginup.php:215
createSessionCommon(integer '1', string 'admin', boolean true, string '88.130.215.64', NULL null)
1: /usr/local/psa/admin/plib/cmd_loginup.php:348
createSessionAdmin(string 'admin', string '************', string '***************************', boolean false)
2: /usr/local/psa/admin/plib/cmd_loginup.php:145
createSession(string 'admin', string '************')
3: /usr/local/psa/admin/htdocs/login_up.php3:27

Please provide a solution. Thank you!
 
Such problem takes place when there is not enough disk space on the server. Please, check it up, espectially / partition.
 
I just started having this exact same problem while trying to backup to FTP repository.

I cannot see how my disk is full, but a disk check via ssh does state it is full. Perhaps when backing up to FTP repository it firsts creates a local copy and then uploads it to the other server? Even still, I didn't realize I was that close to using up all my storage space.

Regardless, if this is the case, and I cannot log in to Plesk to delete backups or easily figure out where my disk space is being used - can someone state where the backup files are stored on the server so I can delete some manually via ssh? I have no idea where they are on the server or how to find them.
