Ok, thank you. I don't know all about my friends. I only wanna play with him, and I don't feel that it's bad. Thank you for your all replies.

Lol, and the problem was caused for him? What is the solution? Can you help me?

I don't know if my friend bought the game. Is it important in this case?

I am the owner, but he only help sometimes

Because a friend told me that

I am so sorry. It's my first server... https://hastebin.com/ipikifuzuq.yaml

Thank you for reply, https://hastebin.com/onihiqevet.properties
