Hey sorry to hear you’re stumped. Recently there have been a lot of issues with older Macs like my 2018 Mini running 10.14.6. The current version of PMS doesn’t work on those, and a fix is in progress.
You should copy your PMS database folder that also has your backups to a safe place.
They are stored on the Mac in
~/Library/Application Support/Plex Media Server/Plug-in Support/Databases
To get running again
- You can do a complete uninstall, then install known working 1.28.2.6151. Fresh server.
- You can do a complete uninstall, then install 1.28.2.6151 and restore backups possibly.
- You can do a downgrade to 1.28.2.6151 and hope it comes back, possibly reclaiming.
Because you’ve done a lot, it’s harder to say, but (3) is the easiest. You reboot the Mac, and make sure PMS isn’t running, then you get the older version unzipped in Downloads, drag it into /Applications and Replace. Give it like 10min before trying to use it in case there’s a bunch of database migration going on.
In recent posts I’ve made for server-mac I gave versions, links, and more instructions, but I’d just be retyping things here and probably not as well. A couple of common words in these topics is Settings Unavailable.
There’s also a bug report I made.
