Problem with chat

Hello,

when i chat, there is a [ ] with the world the player is in before the name of the player. How can i disable it? I use multiple plugins, they are:

1. CClearChat
2. WorldEdit
3. DisableJoinMessage
4. AntiFallDamage
5. ViaVersion
6. Vault
7. ViaBackwards
8. WorldGuard
9. ViaRewind
10. Essentials
11. PowerRanks
12. PlotSquared
13. Multiverse-Core

Please help!

I started the server, wrote a message and stopped it again. Here is the log: https://mclo.gs/sDzY39K

Here is the multiverse config file: https://www.mediafire.com/file…1pwu1e5ss/config.yml/file

Thanks, that helped!

you can close this now.
