Solved Bukkit 1.4.7 R1.0 Won't Spawn Hostile Mobs

I run a survival server for me and some of my friends. A crucial part of the server relies on fighting hostile mobs (creepers, skeletons, zombies, etc) and they won't spawn. I've checked caves, dark places, far away places, everything and no hostile mobs will spawn. I can spawn mobs manually or with monster spawners, but they won't spawn on their own.
My configs:
Essentials: http://pastebin.com/pVwK1LBj
WorldGuard: http://pastebin.com/6dKG5wxB
My server properties file: http://pastebin.com/Wd9CY0vx

My plugins: ChestShop, Essentials, EssentialsSpawn, iChat, iConomy, Lottery, LWC, mcMMO, McMmoReward, MobArena, Modifyworld, MonsterHunt, PaidRanks, PermissionsEx, SetRankPEX, uSkyBlock, Vault, WorldEdit, WorldGuard

 

If you are running Multiverse, make sure you have monsters set to true in there too. To make sure you don't have them spawning somewhere else though, you can run "/wg report" and take a look at the report it creates in the WorldGuard plugin folder.

 

I ran the report, and under the entities for the World no hostile mobs show up. I also don't run Multiverse.

 

Also make sure you don't have the __global__ region a flag like mob-spawning set to deny.

 

Under WorldGuard in the main config? The only thing I found was block-creature-spawn: [] and that didn't have true/false. Whenever I set it to false it just goes back to the undefined state.

 

go to the world you want spawns in... then type /region info __global__

(note... it's DOUBLE underscores at the start and end of that)

EDIT : Also that MonsterHunt addon you have is kind of out of date. If the global flag isn't set to deny mob spawning I would try removing monsterhunt next.

 

Deleted MonsterHunt, no change. I typed "/region info __global__" in and nothing happened. It told me that the region doesn't exist.

 

Ok, did you check your bukkit.yml to make sure you didn't disable their limits there?

 

It worked! Thank you for all of your help!

 

Always a pleasure

 

How did you fix it?!

 

Under the main server directory, the spawn monster limit was 0.

 

where do you see that? copy & Paste please

 

Here's the file I had to change. It's the bukkit.yml under the main directory.
