Server Version#: 4.108.0
I realize that the Plex database files are stored here:
C:\Users(username)\AppData\Local\Plex Media Server\Plug-in Support\Databases
com.plexapp.plugins.library.db
com.plexapp.plugins.library.blobs.db
Can you restore the database (and hopefully watch-state, collections…) from the single zip file that is downloaded from:
Plex / Settings / Troubleshooting / Download Database
If so how?
thanks
