I've been running my server for quite some time and I've never really had problems and when I did, I could usually remove the problem by editing a config file for a specific plugin. Basically, when non-op players place a chest, they can't open it nor can they destroy it. At first I thought it might be one of the protection plugins I have in place so I disabled them one by one. Still having problems and its only a recent thing that has started to happen. Anyways, plugin list: AdminCmd ButtonLock CartJump ChatManager explosionRevert2.1 Falsebook(all of them) Lockette (tried removing and didn't do anything) MCSL MobLoot ModifyWorld NoSuffixedKill OpChatPlugin1.2 Permissions PermissionsEx (added this after the problem appeared to try and fix building rights) PorteCoulissante PreciousStones Ptweaks RollingMinecarts SpawnBed TradeCraft WorldEdit WorldGuard WorldPortal Running Windows 7 32bit, Bukkit 1185 I'm also not getting any errors in chat or console. I've removed WorldGuard, WorldEdit, PreciousStones, Lockette and played with several config options of almost all plugins. For whatever reason, they can place chests and destroy other blocks no problem. I've set myself as Default using PermissionsEx and de-opped myself. I also cannot open and destroy my own chests. Hopefully someone has an idea of what I can try next as it does affect brand new players joining my server Edit: I gave default the '*' permission and it let me open and destroy chests so I'm thinking there is a permission node I'm just missing.
