One of the plugins you are currently using is not visible to new connect players.

So when the player connects, he tries to reload Plugin.

Is there a plugin available?

Uually players cannot reload a plugin (?) or do anything else to them except use the commands they have permissions for.

Sorry, I don't think the meaning was conveyed properly because I am not good at English.

I mean, when the user connects to the server.
Can i make the oxyde.reload "" command work at that time?
