I am not sure what I have done to my Jellyfin install. I have been having various issues with my computer that I am using for Jellyfin and when I fixed one (ran out of hard drive space) I now have this one. I do not believe Jellyfin is starting when I reboot my computer. Here is the output of my logs file:

I googled "There is an error in XML document (0, 0)." and was completely overwhelmed by the posts and solutions I found. Is that even the best starting point for picking this apart?

Can you check your config folder (seems like it's /etc/jellyfin for you) for migrations.xml and system.xml? I'm guessing if you were low on disk, jellyfin tried to write to them, but couldn't, so it left empty files which it can't now read from.

Thank you so much for your help! I went to that folder and the migrations.xml was a blank file, but system.xml was still okay.

I searched a little about the migrations.xml and found a thread on the jellyfin forum with exactly the same problem so I renamed all of the xml files in the /etc/jellyfin folder and it started back up nicely.

Good to hear. I think jellyfin could be improved so that it doesn't completely clear migrations.xml every time a new migration is applied when it starts up (switch from a Create to an OpenOrCreate on the file). Although a low disk situation can be difficult for software to deal with typically anyway.
