As of my last update in September 2021, the behaviour you described where the Default Reseller Owner in WHM (Web Host Manager) changes automatically has not been reported as a common issue or default behaviour. However, software and platforms like WHM may have undergone updates or changes since my last update, which could lead to different behaviors.
In general, if you are experiencing unexpected changes in the Default Reseller Owner in WHM, there could be several potential reasons:
1. Software Updates: WHM or the underlying server software might have been updated or modified, leading to unintended changes in settings.
2. Security Breach: If your WHM system has experienced a security breach, unauthorized access could result in changes to the settings, including the Default Reseller Owner.
3. User Error: A user with the appropriate permissions might have inadvertently changed the Default Reseller Owner.
4. Automation or Scripting: There could be scripts or automation in place that interact with WHM, causing the changes.
To investigate and resolve the issue, consider the following steps:
1. Check Server Logs: Examine the server logs for any unusual activity or unauthorized access. Look for any entries related to changes in the Default Reseller Owner.
2. Review User Activity: If there are multiple users with access to WHM, check if any of them have made changes to the settings recently.
3. Update WHM: Ensure that you are using the latest version of WHM and cPanel to minimize the risk of bugs or security vulnerabilities.
4. Review Automation: If there are any scripts or automated processes interacting with WHM, verify that they are functioning correctly and not causing unintended changes.
5. Password Security: Ensure that strong passwords are in place for all users with access to WHM to prevent unauthorized access.
6. Contact Support: If you have checked the above steps and are still experiencing the issue, consider reaching out to cPanel support or the support team of your hosting provider for assistance.
As always, when dealing with any critical system changes, it is recommended to proceed with caution and have backups in place to revert to a previous state if needed.
