Most users, however, will not need to change these Plex server settings, and doing so can cause problems with your Plex Media server. If you would like to find and change these settings, you can use the information below.

Fixing settings issues
If you have issues with your Plex server after changing any of the above hidden settings, such as some Plex server settings missing, you can reset the values back to default by deleting either the preferences file or the keys in the Windows registry.
Deleting the preferences file will reset any changes you have made, and you will also lose any server shares or Mobile Sync items you may have. Your Plex Media Server library database will not be affected.
In addition to the above hidden settings, you can also have Plex enable syslogging on a Linux-based system. This can be done by setting the configuration variable:
The variable will need to be added to the Plex Media Server configuration file. This file is located in the following locations:
Config File Location: /etc/sysconfig/PlexMediaServer
Config File Location: /etc/init.d/plexserver
Config File Location: /var/packages/Plex Media Server/scripts/start-stop-status
Ubuntu 15 (and older)
Config File Location: /etc/default/plexmediaserver
Ubuntu 16 (and newer)
Config File Location: /etc/systemd/system/plexmediaserver.service.d/override.conf
