Cause

System utilities (curl, wget, php, etc.) are not accessible for the subscription user.

Resolution

One of the following workarounds may be applied:

1. Recreate the task from under a root user at Tools & Settings > Scheduled Tasks:

   CONFIG_TEXT: Task type: Run a command
   Command: /opt/plesk/php/7.2/bin/php -q /var/www/vhosts/example.com/httpdocs/whmcs/crons/cron.php

   OR

   CONFIG_TEXT: Task type: Run a PHP script
   Script path: /var/www/vhosts/example.com/httpdocs/whmcs/crons/cron.php
   Use PHP version: select any required version
   System user: root

2. Provide the system user john_doe with access to the server over SSH (for example, /bin/bash) at Domains > example.com > Web Hosting Access.

3. Change the crontab shell for scheduled tasks to /bin/bash at Tools & Settings > Scheduled Tasks > Settings.

4. Add a required command to chrooted environment.
