While poking around, and regarding our conversation about the private key setup Plex has, I noticed that in Preferences.xml the PlexOnlineToken variable is blank.
PlexOnlineToken=""
As I have never bothered to check this on a working machine, I don’t know what to expect, or if this gives us any information, but I felt it was worth noting.
With Plex stopped, remove PlexOnlineToken="" from the Preferences.xml, save, and restart
After exiting the editor, verify the file is still owned by plex:plex
If that is the root cause of this, it is the weirdest failure to write the file I’ve seen.
To be clear, do you want me to remove the variable and the value within the quotes, or just the value within the quotes on PlexOnlineUsername and PlexOnlineEmail?
