The Lua and JavaScript extensions for Oxide haven't been supported nor developed in years, you should remove them.

Where are these scripts?

RustDedicated_Data/Managed/Oxide.Ext.JavaScript.dll and Oxide.Ext.Lua.dll, likely installed by you or your host through their control panel.

That isn't really the same problem, that's a different error. That error means Oxide either isn't fully installed or is missing files.

is because, at the time I open the server, it appears this error

and when the server is open and I put the plugins, it gives that other

Like I mentioned, first error with Oxide.Ext.JavaScript is because of you having a 2+ year old extension installed; you'd need to remove it in the location I mentioned previously.

I already removed them and every time I'm starting, I check again to see
when I start the server with the plugins in the oxide folder, this other error appears

Sorry for my english, if you have many mistakes, I'm Brazilian.

Without seeing the full log, hard to tell what the tiny portion of an error is coming from.

How can I tell you everything?
