so right now my best bud Jaidantate and his best bud Fluffyjack are in a server named "parkour" But everytime i join it, it is an empty room.

IT is because they did (for example) /jo parkour boss


They didn't really do jo parkour boss. But when you go into the server list, it should be able to show the two parts of the server name.

Are you sure they did it in 2 words?

Cause I don't think you can use spaces in the server name. Try /jo parkourboss

They did do it in 2 words. You CAN use spaces in server names, but the fact is, on the forums and on the server list, you can only see the first word

Just don't use two words.
It doesn't need to be "fixed", you just have to follow the command syntax.

Had this problem even when I used one word.
