Having same issue (repeatedly) as @Ksullivan86 (above).
Had issue a month ago, performed “Restoring a Backup” as found in:
Restore a Database Backed Up via ‘Scheduled Tasks’ | Plex Support
…and it fixed the problem.
…for about 3 weeks…then it came back again.
I’m willing to work with you; restoring a database when an update accidently messes something up; but to then have it occur again is getting ridiculous.
Let me know if you need logs, screen prints or anything that would help.
*** Update: Went into Databases subdirectory as described in the above link, backed up the directory, and the deleted all files that begin with tv.plex.providers.epg*
That appears to have deleted my DVR within Plex, but kept my DVR Schedule. I then easily re-added the DVR, and now it works (again). We’ll see how long that lasts…
