Example error in the console:
The plugin is called to help solve this problem (at least try)

Installation:
The plugin is cross-platform (Supports: spigot, paper, bungee, velocity)

If you have 1 or more spigot/paper servers, install the plugin in the plugins folder on all your spigot/paper servers
