On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Plesk for Linux kb: technical

Applicable to:

  • Plesk for Linux

Symptoms

  • Litespeed extension is installed and broken:

    PLESK_ERROR: ERR [1] ERROR: Class 'Lsc\Wp\WPInstallStorage' not found (PleskPanelWPInstallStorage.php:25)

  • Sites can show: 

    CONFIG_TEXT: 404 Not Found

Cause

Web-server misconfiguration. Both Apache and Litespeed are running at the same time on Plesk server:

CONFIG_TEXT: # ps auxwwff | grep httpd
root 236635 0.0 0.1 885164 61336 ? Ss Jul13 14:07 /usr/sbin/httpd
root 1148790 0.4 0.4 186500 159296 ? S Aug19 3:21 litespeed (lshttpd)

Resolution

  1. Login to the server via SSH.
  2. Switch Web-server to Apache:

    # /usr/local/psa/admin/bin/modules/litespeed/lsws_cmd "/usr/local/lsws" SWITCH_TO_APACHE

  3. Remove Litespeed extension:

    # plesk bin extension --uninstall litespeed
