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?

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.
