I have googled my ass off, I have also search on any plugin but can't find the causing because whenever someone try's to open a chest it says You are not allowed to open this here which makes me believe it's from World Guard Code: # # WorldGuard's configuration file # # About editing this file: # - DO NOT USE TABS. You MUST use spaces or Bukkit will complain. If # you use an editor like Notepad++ (recommended for Windows users), you # must configure it to "replace tabs with spaces." In Notepad++, this can # be changed in Settings > Preferences > Language Menu. # - Don't get rid of the indents. They are indented so some entries are # in categories (like "enforce-single-session" is in the "protection" # category. # - If you want to check the format of this file before putting it # into WorldGuard, paste it into http://yaml-online-parser.appspot.com/ # and see if it gives "ERROR:". # - Lines starting with # are comments and so they are ignored. # iconomy: buy-on-claim-price: 1.0 enable: false buy-on-claim: false protection: enforce-single-session: true item-durability: true remove-infinite-stacks: false chest-protection: enable: false physics: allow-portal-anywhere: false no-physics-sand: false no-physics-gravel: false ignition: block-tnt: false block-lighter: false regions: max-region-count-per-player: 7 claim-only-inside-existing-regions: false max-claim-volume: 30000 high-frequency-flags: false enable: true use-scheduler: true wand: 287 simulation: sponge: redstone: false enable: true radius: 3 classic-water: false fire: disable-lava-fire-spread: true disable-all-fire-spread: false suppress-tick-sync-warnings: false spawn: login-protection: 3 exact-respawn: false teleport-to-home-on-death: false kick-on-death: false spawn-protection: 0 mobs: anti-wolf-dumbness: false block-creeper-block-damage: false block-creeper-explosions: false blacklist: use-as-whitelist: false logging: console: enable: true file: path: worldguard/logs/%Y-%m-%d.log enable: false open-files: 10 database: dsn: jdbc:mysql://localhost:3306/minecraft enable: false table: blacklist_events user: root pass: '' summary-on-start: true weather: always-raining: false disable-powered-creepers: false disable-weather: false disable-lightning-strike-fire: false always-thundering: false disable-thunderstorm: false disable-pig-zombification: false crops: disable-creature-trampling: false disable-player-trampling: false op-permissions: true pumpkin-scuba: false player-damage: teleport-on-void-falling: false disable-drowning-damage: false disable-mob-damage: false disable-explosion-damage: false disable-void-damage: false disable-fall-damage: false disable-fire-damage: false disable-contact-damage: false disable-suffocation-damage: false disable-lightning-damage: false disable-lava-damage: false teleport-on-suffocation: false Further these are my Plugins (Alot) AdminCMD bColoredChat bSwarm ButtonWarp Citizens ColorSheep CopyCat DeathSpawn DispNameChanger EasyPM Jail LazyRoad LoginMessage QuikStrasse Seasons SetSpeed SimpleAutoReply SimpleGive SimpleHome SimpleJail SimpleSave SimpleSignEdit SimpleWarp SpawnMob SpawnX src StarterKit StruckDown Tips ToughMelt TpPortal TPportals TradeCraft VanishNoPickup WarpWiz WolfPound WordReplace WorldEdit
