Kick flight on join

Players get kicked while installing the resourcepack

The kick problem

Some servers may think you're flying while the resourcepack is installing, depends on where is your spawn location.

You may get this error: "Flying is not enabled on this server", or getting kicked by an anticheat.

How to fix?

Disable the hide-hud feature in the config.yml file of ItemsAdder.

  protect-player:
    black-screen: true
    hide-hud: false

Still having the issue

Enable this option in server.properties file:

server.properties

allow-flight=true

This setting will not make your players to be able to fly, just Minecraft server will not kick them on flying without permission. To prevent hacking because of this setting, is good to use an AntiCheat.
