Plex Media Server Warning ‘Not Found’ Errors (Fixed)

The media browser on my LG TV has been acting up recently. Instead of listing the categories set up in Plex it pops up a dialog saying “Warning: Not Found”. It does this despite being able to see the Plex Media Server (going to ‘bowse sources’ or similar brings up the server’s name but selecting it gives the same error).

Fortunately Dunhillsmoker on the Plex forums had a solution:

  1. Stop plex service – sudo service plexmediaserver stop
  2. In Plex Plugins directory remove System and Framework bundle directories:
    • mv /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Plug-ins/System.bundle/ ~/plex
    • mv /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Plug-ins/Framework.bundle/ ~/plex
    • (note, depending on permissions you may need ot be root to do this)

    • Start plex service again: sudo service plexmediaserver start
    • This sorted the problem for me.

  1. Thanks so much for this post! I tried a lot of other things. What originally cued me that there was an issue was the lack of plugin support. I couldn’t use any of my channels. Digging further, I realized that my metadata stopped processing many months ago. After I deleted the system and frameworks, I restarted the server, refreshed data and everything works now! Thanks again!
