- Plesk 12.5 for Linux
Plesk is managed via XML API requests.
Login is performed by a session token with
variables to make redirection back to panel.
Logging out of Plesk generates following error:
ERROR: Call to undefined method Plesk\\Session\\Context::getSessionId() (logout.php3:105)
This behaviour is recognized as software issue #PPPM-4585 that was fixed in Plesk Onyx.
Upgrade to the latest Plesk version .
