Basically i removed essentials anti-build as it was causing problems... i use world guard with some flags for regions but players can still destroy hedge. grass & flowers in the spawn..also they can destroy glowstone?! Any good anti-grief plugins i can install where they just cant break anything.
DMstratz. Make sure you claimed the worldguard area properly. Solutions: 1.) Reclaim the spawn area properly 2.) Add these flags: build:deny pvp:deny mob-spawning:deny 3.) Done. If its not working, then try using Factions Safezone.
