I downloaded the mod and installed it, loaded the server up once and all the other plugins loaded but the car spawn settings did not make a config file

Did the server logs say that Car Spawn Settings was loaded? Can you paste the output of running the oxide.reload CarSpawnSettings command? See if that will create the config file. Also, was this a fresh map wipe?

I attempted to reproduce this by deleting the config and starting the server, but the config generated fine - no issue.

Where do I put that command, in console in game or the server console?

Server console, but you could also put it in client console if you have sufficient admin privileges.

So I reinstalled the whole thing and it still didn't work even with the command you gave me, thanks for the help but I have no clue what is wrong.

It's going to be even harder for me to help if you don't do what I ask, and don't answer my questions. I asked you to paste the output of that command. Did it say for example, "Car Spawn Settings reloaded successfully", or "Car Spawn Settings loaded successdully", or something else (or nothing)? These have different meanings and will point us in different directions to troubleshoot further.

If you single want to get the plugin working, you could try copying the default config from the plugin docs. However, I would like to root cause the issue in case it could happen to other users. You can DM me your Discord username and I can also troubleshoot we with you more closely.

Merged post

Someone recently reported a similar issue for another plugin I maintain.

The issue had to do with the server or Oxide installation, not the plugin itself.

Sorry got it working and forgot about the ticket. Yeah oxide was a bit messed and didn't load that specific plugin. It works now though so do not worry.
