I just manage to install multicraft with spigot on my vps, everything is fine, I can connect and play the vanilla minecraft. Then I run across some problem with plugins. I manually upload plugins into the server's plugin folder: /home/minecraft/multicraft/servers/server1/plugins Then I restart the server, but the plugins are not working. I check the log, every plugin output some similar errors: Failed to write config /home/minecraft/multicraft/servers/server1/plugins/Essentials/config.yml Is this related to permissions? Or am i doing something wrong the installing plugins? What can I do to solve this? Thanks!
