Hey. I really need some help with my server. It's being hacked by thousands of hackers, and theyre not hackers who use nodus, Zombies mod pack, etc. oh no! They go onto my server, OP themself, and their teammates,bans members, and then starting shifting spawnpoint, WorldEditing every town, house, spawnpoint, etc. Don to the ground. And then I turn my server off. Checks the server log, but I don't see anything unusual. Just logins, chat, and such. They actually does that When I open my server again, it crashes automatically because of too much changes to the map. (Yes, I'm not running on more than 2,15 GB Ram, so it crashes when that happens) Info: IP: survival.frozenmc.com Online mode: TRUE Plugins: NoCheat, Factions, GroupManager, Essentials, EssentialsSpawn, EssentialsProtect, EssentialsGroupManager, EssentialsGroupBridge, EssentialsChat, Lockette, Mobdisguise, BOSEconomy, WorldEdit. I've seen other servers who manages to stop these hackers from doing this sh*t.. Can anyone please help?
