alright so heres my problem, when i try to put it on aternos it could be paper or spigot i try always the earliest version, it cannot be enabled even though im using 1.17.1 paper/spigot i try older 1.17.1 versions and the commands ARE a thing and when i do /plugins the plugin appears in green as if it was enabled but when i die or kill someone or get killed nobody loses hearts its just all fine when i do /lsreaload or /lifestealreload it says in the chat: reloaded! still the same issue how can i exactly fix this?
