is there any settings to change to hide these commands and errors from the user, or can this only be achieved with plugins?
turning off op did infact remove the give x player from chat but the error still remained, even moved my self out from OP Group In PurePerms edit: This is cause from the plugin im using, fixing it now.
you may have to disable it by editing the plugin if it's not flexible enough to hide errors but you should just remove that thing that make player execute the non existance command
