Troubleshooting Tips

If you run into issues while hiding Zimbra from search engines, check the system logs first — most errors leave a clear trace in /var/log/.

If a step fails consistently, verify file permissions and ownership, as incorrect permissions are a common cause of silent failures on Linux servers.
