How should I allow fights

[SilianZ]

I am using this mod to connect with my friend, but there is no "allow fight" option in the setting, which leads to that when I use the “Majo's broom” with him, I will always be kicked out for the reason of "Flying is not enabled on this server". *I don't know how to open a server.

Which version are you using?

I don't know much, this is I help other people to ask. 不知道，这是我帮别人问的。
