the players name was seeming to be normal but i think he had some special char or something? could you tell me how to fix this or what the error means

Ban by steamid in console instead

I tried both and he didnt get kicked/banned player admin shows him in the banned tab but everytime i issued a command steamid or username i got that error did it in console and player admin

try in console while that plugin is unloaded?

Well upon further investigation it seems its not just this plugin that has this issue as i installed server armour to test that and i get the same type of error..

@thedeejay this seems related to your filesystem.

Try updating your server, and reintalling oxide again. If the problem persist make sure the permisisons on everything is fine

It worked on other players it was just this one player specificly - i have doubled checked permissions as oxide was just reinstalled on force wipe and is currently up to date everything by all intents and purposes is correct as far as i can tell.

You can PM me the player details, however if it does the same with the player steamid then there is something else wrong. 

This error doesn't appear to be plugin-related, rather something with the Rust server console.
