Players take damage in spawn world but do not in all other worlds, not even in the nether. You can even fall in the void and survive. Any idea what might be causing this and on how to solve it please? Thanks.
My guess, is that you have a plugin that is prohibiting PvP in every world except for the spawn world. What all plugins do you have installed?
Not just pvp but all forms of damage. Plugins On Server; AdminFun v1.0.0, BlockSniper v1.2.0, InvSee v0.0.1, BuyCraft v1.2.2, LiveXYZ v0.5.0-alpha, ManyWorlds v2.0.3, PeacefulSpawn v2.5, StatsPE v2.4.12, AdvertisingKick v1.0.0, HereAuth v1.0, OyuncuBuyukluk v1, ZipPluginLoader v1.2.1, ClearLagg v1.1.0, AntiSpam v1.3, Farms v1.0-non-alpha, EasyMOTD v1.0a, SignWarp v1.5.1, iProtector v3.1b, WorldGuard v1, essentialsTP v1.1.0, RandomEnchant v1.0.3, PocketVote v1.2.0, SlapperRotation v1.0.1, SAC v3.2.1, BanItem v2.2, CustomAlerts v1.6, RestartMe v1.3.0, MagicWE v0.2.7, PurePerms v1.4.0-INDEV, AdvancedKits v5.1, Slapper v1.3.3, TopVoter v2.0.10, AlwaysSpawn v2.2.2, PureChat v1.4.0
I think that it's probably either PeacefulSpawn, iProtector, or WorldGuard prohibiting the damage. It might also be a combination of all three. Try taking each of those out one by one to see if any of them are your problem. And if not, than I don't know.
