So the plugin has been in my server for a long time and hasn't been working, the plugins is always unloaded and i have tried reinstalling it into the server, but the same thing happens which is that it doesnt work and say unloaded. Can someone please help. I have checked my logs and it says enable a ban system but i dont know where or what too look for.
