Hello iam new here to the Rust  community but i am running a my very first rust server but the wierd thing is yestoday everything worked just fine and now the oxide wont show when i start the server. cant use plugins or anything right now anyone got a clue why...

Sounds like you do not have Oxide installed. I'd suggest re-installing Oxide, and make sure you aren't updating it afterward, as that would remove the mod.

thats the thing when i install oxide the first time i got the odixe folder now when i moved the folder it to a diffrent harddrive i wont work

If it "doesn't work", but the server is starting and running, then you do not have Oxide installed. I'm not sure how that may have happened in your case, but generally it's from updating the server with Steam.
