  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Issue error 500 Session_Exception login to Plesk

The locale which had been previously chosen as a default was unregistered from the Plesk database during a Plesk upgrade.
Try to fix it with the following steps:
  1. Set the locale en-US as default:
    Code:
    # plesk bin server_pref --set-default -locale en-US
    # plesk bin admin -u -locale en-US
  2. Reinstall Plesk updates:
    Code:
    # plesk installer update --repatch
  3. Log in to Plesk and set a required locale at Tools & Settings > Languages.
