I have the mod installed in the client, and when I use it in as server most services like info overlay or shapes work great, but when I want to see for example Nether fortress delimiters, they don't show up. It does not look like a config problem because when I have the same ones in a single player world it works perfectly. Maybe there's something I have to do to make it work. By the way, installing it in the server does not make it work neither. Thanks in advance.

Oh okay, didn't know that, thank you very much!

The server would need to have the Servux mod for the structure bounding boxes to work in MiniHUD. MiniHUD itself is client-side only and can't be used on the server side.
