Error setting up debug logging

[theguymadmax]

Standard: 

{
    "Serilog": {
        "MinimumLevel": {
            "Default": "Information",
            "Override": {
                "Microsoft": "Warning",
                "System": "Warning"
            }
        },

The log file should be should be change to 
{
    "Serilog": {
        "MinimumLevel": {
            "Default": "Debug",
            "Override": {
                "": "Debug"
            }
        },
after the server has been on, otherwise you'll see the error message. if you restart with this config you'll see very verbose logging, which isn't helpful. 

The guide has now been updated here: https://github.com/jellyfin/jellyfin.org/pull/1660
to say use 

{
    "Serilog": {
        "MinimumLevel": {
            "Default": "Debug",
        },

You can set this at any point; it won't get that error now and will fallback to verbose logging.
