so i have a server with some friends on server.pro.

we wanted to install dynmap on it but after i downloaded the spigot version for it (Dynmap-3.0-beta-5-spigot) i cant find the file for adjusting it.

this is what the console is saying:

Many thanks for the help in advance!

Outdated release. This one is the latest one: https://dynmap.us/releases/Dynmap-3.0-beta-10-spigot.jar
