I think its not... i was delete some plugins that maybe block user to eat food. I've been deleted DeathControl. But i still not working...
I was working hard to find the problem.. Also i was rolling back my action to the server.. but it does nothing. Still have a problem and its serious problem. Now im trying to inspecting world guard activity. It maybe the problems. But if you know anything about this you can answer it, also i need an answers fast. My server is already opened to the public but still have a serious problem about "Cant eating foods"
If you want to check it you can ask me in conversation and join my server, you may know whatis the problem. #notAdv.

Ah.. i found the problem:
My server was setted to peacefull difficult mode and i doesnt know about that. I was reading mincraft wiki and here is the explained of difficult mode:

Peaceful: No hostile mobs can spawn naturally, except shulkers and the ender dragon, which do not deal damage. Also, no spiders, cave spiders, zombie pigmen or endermen – neutral rather than hostile mobs – can spawn naturally. When any of these mobs attempt to spawn (whether naturally, through mob spawners, spawn eggs, or commands), they are removed from the game instantaneously. Switching from any other difficulty setting to Peaceful removes existing hostile mobs and the neutral mobs listed above, except for shulkers and the ender dragon, and except for neutral mobs currently hostile to the player such as polar bears, wolves, iron golems. Wolves and polar bears will still remain hostile to the player, though will be unable to inflict damage; llamas can still damage the player. Players regain health over time. Despite regaining health over time, it is still possible to die if damage is received quickly enough. The hunger bar never depletes and players cannot eat anything except golden apples and chorus fruits, unless the player has switched to Peaceful when their hunger bar was below the maximum. Additionally, If the hunger bar is below the maximum, it quickly regenerates.
