Spawn is automatically protected?

For some reason, the spawnpoints of all my worlds are automatically protected and can only be edited by OPs. I disabled primitive spawn protection in Essentials and I don't have WorldGuard installed. I do use MultiCraft, but I don't think that changes anything. Here's the list of plugins I have:

Code:

Lockette, bLog, Permissions, DCReason, PathBuilder, TotallyOrbSome, MultiInv, SimpleCensor, iZone, WorldEdit, Simple Prefix, PvPToggle, WhoPlacedIt, Multiverse-Core, Essentials, Multiverse-SignPortals, EssentialsSpawn, EssentialsProtect, EssentialsChat, PermissionsBukkit

 

Possibly the built-in CraftBukkit spawn protection? Check in your bukkit.yml file, see if you've got spawn-radius: 0, and if not, set it to 0.

 

That was it, thanks!
