Advanced, Hidden Server Settings

There are a number of advanced, hidden Plex Media Server settings, some of which are not available from the normal interface. Instead, they're available where your Plex Media Server stores its own settings. The vast majority of users will never need to alter these settings. We recommend exercising caution when considering altering these settings.

If you get into trouble, you can reset the Server to default by deleting the preferences file or Plex entries in the Windows Registry. If you delete the preference file, you will need to reset any changes you've made and you will also lose any server shares or Mobile Sync/Cloud Sync items you may have. Deleting the preferences file will not affect your Plex Media Server library database.

Locating the Advanced, Hidden Settings


On Windows, the preferences are available in the registry. To access settings related to Plex Media Server:

  1. Open the "regedit" application
  2. Navigate to Computer\HKEY_CURRENT_USER\Software\Plex, Inc.\Plex Media Server
  3. Create a new entry named as per the options below and add the correct value, or else edit an existing value

macOS / OS X

On Mac computers (macOS or OS X), the preferences are available under your computer user account library preferences.

Using the Finder's "Go" menu, select Go To Folder... then enter the following in the dialog box that pops up:


You can then open that file (which is really XML) in a text editor to add new settings or edit existing ones.

Warning!: If you use a text editor to make changes, you will need to reboot the computer to have the changes take effect (since the OS caches the preferences).

Alternatively, you can open the "Terminal" application and run commands to add/alter values.:

defaults write com.plexapp.plexmediaserver <optionname> <value>
defaults write com.plexapp.plexmediaserver <optionname> -boolean <Value>


Preferences File

On Linux the options are available in a XML file called Preferences.xml, which is located in your Plex Media Server data directory.

Add a new XML attribute with the name of the option and the value. e.g.:

<?xml version="1.0" encoding="utf-8"?>
<Preferences BlacklistedBundle="" newoption="withvalue"/>

Note that the Preferences tag can contain a lot of options already.

Syslog Option

In addition to the Preferences file, as of Plex Media Server, it's also possible to enable syslogging. This is done via a configuration variable: PLEX_MEDIA_SERVER_USE_SYSLOG=true

To set the variable, it has to be added to the configuration file of Plex Media Server. Here is where to place it on various Linux distributions:

  • CentOS/Fedora: Add export PLEX_MEDIA_SERVER_USE_SYSLOG=true under /etc/sysconfig/PlexMediaServer
  • ReadyNAS: Add export PLEX_MEDIA_SERVER_USE_SYSLOG=true under /etc/init.d/plexserver
  • Synology: Add PLEX_MEDIA_SERVER_USE_SYSLOG=true under /var/packages/Plex Media Server/scripts/start-stop-status
  • Ubuntu: Add PLEX_MEDIA_SERVER_USE_SYSLOG=true under /etc/default/plexmediaserver

After adding the variable, restart Plex Media Server. Logs from Plex Media Server will then be output to syslog instead of normal server logging.
