Starting on October 19, 2021, we will enable 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.
To be prepared for this change and to avoid the need to register during your next ticket submission after the change, we encourage you to create an account here before October 19 using the same email address as your current 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. You will continue to use ZenDesk authentication until we switch over to single-sign-on on October 19th.

After removing a sub-domain with WordPress instance, the following error message appears in Plesk/WordPress Toolkit (ID in the error message may vary):

PLESK_ERROR: Can not find domain by id 123

This error message may also appear:

  • in email notifications about application updates sent form Plesk to a domain owner:

    PLESK_INFO: Updates were not installed for the following items:
    1. Instance "My CMS" (https://example.com): Can not find domain by id 123

  • when trying to remove a WordPress plugin that was installed on the deleted domain:

    PLESK_ERROR: Installation "example": Can not find domain by id 123"

  • when searching for this domain using Plesk search.

  • in a Linux command-line interface, when running the Plesk Daily Maintenance task:

    # /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php
    ...
    ERR [panel] pm_Exception: Can not find domain by id 123

  • in the Plesk logfile /var/log/plesk/panel.log on Linux or in %plesk_dir%admin\logs\php_error.log on Windows Server:

    CONFIG_TEXT: Failed to generate screenshot of instance #5: URL of instance #5 is empty
    ERR [extension/wp-toolkit] Can not find domain by id 123

  • Unable to remove Wordpress instance via Applications. The following message is returned on a blank page:

    CONFIG_TEXT: {"status":"success"}

  • Instances were previously removed via filesystem in /var/www/vhosts/example.com/httpdocs

Cause

Product issue:

  • #EXTWPTOOLK-2454 "WordPress Toolkit now properly cleans up its database when a subdomain with WordPress installation is removed in Plesk."
    Fixed in:

Resolution

Please consider updating your server:

Workaround

As a workaround, update WordPress Toolkit to the latest version. In case the issue persists, use the following workaround:

Click on a section to expand

For Plesk Onyx on Linux Server

  1. Connect to the Plesk server via SSH.

  2. For security purposes, create a dump of the Plesk database:

    # plesk db dump psa > psa.sql

  3. Remove leftovers from the Plesk database:

    # plesk db "truncate longtasks"
    # plesk db "truncate longtaskparams"

  4. For security reasons, create a backup of the WordPress Toolkit database:

    # cp -p /usr/local/psa/var/modules/wp-toolkit/wp-toolkit.sqlite3{,.backup}

  5. Access the WordPress Toolkit database in SQLite:

    # sqlite3 /usr/local/psa/var/modules/wp-toolkit/wp-toolkit.sqlite3

  6. Enable headers:

    MYSQL_LIN: sqlite> .headers on

  7. Get a WordPress instance ID using the domain ID from the error message. In this example, domainId is 123:

    MYSQL_LIN: sqlite> select instanceId from InstancesDomains where domainId=123;
    instanceId
    567

    Note: There might be several instances, make sure to execute the next step for each of them.

  8. Remove all corresponding information:

    MYSQL_LIN: sqlite> DELETE FROM Instances where domainId=123
    sqlite> DELETE FROM InstanceProperties WHERE instanceId=567;
    sqlite> DELETE FROM InstancesDomains WHERE instanceId=567;
    sqlite> DELETE FROM Instances where id=567;

  9. Exit SQLite:

    MYSQL_LIN: sqlite> .quit

For Plesk Onyx on Windows Server

  1. Connect to the Plesk server via RDP.

  2. Start a command prompt as an Administrator

  3. For security purposes, create a dump of the Plesk database:

    C:\> plesk db dump psa > C:\psa.sql

  4. Remove leftovers from the Plesk database:

    C:\> plesk db "truncate longtasks"
    C:\> plesk db "truncate longtaskparams"

  5. Download a bundle of command-line tools for managing SQLite database files and extract the file sqlite3.exe.

  6. Copy the sqlite3.exe file to the %plesk_dir%var\modules\wp-toolkit folder.

  7. Open the %plesk_dir%var\modules\wp-toolkit folder and create a copy of the WordPress Toolkit database wp-toolkit.sqlite3.

  8. Start sqlite3.exe located in %plesk_dir%var\modules\wp-toolkit and access the WordPress Toolkit database using the command:

    C:\> sqlite> .open wp-toolkit.sqlite3

  9. Enable headers:

    MYSQL_WIN: sqlite> .headers on

  10. Get a WordPress instance ID using the domain ID from the error message. In this example, domainId is 123:

    MYSQL_WIN: sqlite> select instanceId from InstancesDomains where domainId=123;
    instanceId
    567

    Note: There might be several instances, make sure to execute the next step for each of them.

  11. Remove all corresponding information:

    MYSQL_LIN: sqlite> DELETE FROM Instances where domainId=123
    sqlite> DELETE FROM InstanceProperties WHERE instanceId=567;
    sqlite> DELETE FROM InstancesDomains WHERE instanceId=567;
    sqlite> DELETE FROM Instances where id=567;

  12. Close the sqlite3.exe window.

    Just in case this helps anyone: I had this error and "select instanceId from InstancesDomains where domainId=123;" wasn't returning anything.  I searched in the Instances table instead: "select * from Instances where domainID=123;" and was able to get the InstanceId that way.

    In my case the InstanceId was actually associated with a different domainId in InstancesDomains:

    select * from InstancesDomains where instanceId=789;
    instanceId|domainId
    789|124

    After double checking that the domain in question (can be gotten from "select * from Instances where domainID=123;" )was indeed removed from Plesk, I ran the delete commands on instanceId 789 and that solved my problem.
