Server Components are missing in Plesk

Applicable to:

  • Plesk for Linux


  • The Server Components list is empty at Plesk > Tools & Settings > Server Components.

  • Mail tab is absent in the Tools & Settings menu and domain menu.
  • There are orphaned Plesk Installer processes:

    # ps aux | grep install
    root 758 0.0 0.0 3876 1388 pts/0 Sl+ 23:10 0:00 plesk installer
    root 762 0.6 0.2 212784 5060 pts/0 S+ 23:10 0:00 /var/cache/parallels_installer/parallels_installer_CentOS_7_x86_64_3.21.1
    root 808 0.0 0.0 112600 984 pts/3 R+ 23:10 0:00 grep --color=auto install


During Plesk update connection to database server was lost as a result Plesk did not reload updated packages list. That issue considered to be a software issue #PPPM-4817 and would be fixed in future product updates.


  1. Install latest Plesk micro updates:

    For Linux

    # /usr/local/psa/admin/sbin/autoinstaller --select-product-id plesk --select-release-current --reinstall-patch --install-component base

    For Windows

    Execute the following in command promt:

    C:\>"%plesk_bin%\ai.exe" --select-product-id panel --select-release-current --reinstall-patch --install-component base

  2. Go to Plesk > Tools & Settings > Server Components and click the Refresh button.
