Plesk for Linux kb: bug

Applicable to:

  • Plesk for Linux

Symptoms

  • Plesk migration or execution of the plesk repair web command fails with the following error message:

    CONFIG_TEXT: Details: PHP Fatal error: Uncaught Error: Class
    'GuzzleHttp\Promise\Create' not found in
    /opt/psa/admin/plib/modules/<extension>/vendor/guzzlehttp/promises/src/functions.php:55

  • Despite WordPress being installed on a subscription, WordPress-related options like Log in; Check Security; Plugins; Themes; Clone; Copy Data are not available at Plesk > Subscriptions > example.com; instead an option to Install WordPress is displayed.

Cause

This is a WordPress Toolkit bug with ID EXTWPTOOLK-8246, which was fixed in WordPress Toolkit version 5.7.2.

Resolution

  1. Connect to the Plesk server via SSH.

  2. Reinstall the Plesk extension which is mentioned in the error message. For ie, if the error was:

    CONFIG_TEXT: Details: PHP Fatal error: Uncaught Error: Class
    'GuzzleHttp\Promise\Create' not found in
    /opt/psa/admin/plib/modules/nodejs/vendor/guzzlehttp/promises/src/functions.php:55

    Reinstall the nodejs extension, as seen above:

    # plesk bin extension --uninstall nodejs

    # plesk bin extension --install nodejs

It's also possible just copy missed files to affected extension directory:

# cp /usr/local/psa/admin/plib/modules/wp-toolkit/vendor/guzzlehttp/promises/src/Create.php /usr/local/psa/admin/plib/modules/spamexperts-extension/library/vendor/guzzlehttp/promises/src/Create.php

# cp /usr/local/psa/admin/plib/modules/wp-toolkit/vendor/guzzlehttp/promises/src/Utils.php /usr/local/psa/admin/plib/modules/spamexperts-extension/library/vendor/guzzlehttp/promises/src/Utils.php

    I had the same error trying to restore a backup. Reinstalling nodejs resolved the issue
