PermissionsEx & WorldGuard problem

Hello. I am having problem setting up PermissionsEx in my bukkit server. I have WorldGuard on and it works when I remove the modifyworld.* node. When I remove it people cannot talk or break any blocks even outside of the protected spawn area with WorldGuard. When I enable modifyworld.* people and break blocks everywhere and bypass my WorldGuard protected spawn. Here is a list of my plugins:
AntiCheat
Essentials
EssentialsChat
EssentialsProtect
EssentialsSpawn
Factions
Lockette
MCMA
Mcore3
Modifyworld
PermissionsEx
WorldEdit
WorldGuard.

 

modify world must be a PEX thing, i use GM so I am unfamiliar with it. However, have you flagged you region to stop people from editing there?
/region [REGION ID] flag build deny
Although, not needed, but i would give it a try. Also, could we see your groups.yml file? This way we can see your perm list for your users and make sure they don't have a perm to override world guard. please post it to pastebin.

modifyworld.* gives users all essential permissions like using the chat, build/break blocks etc. Removing this node works because you are denying all users permissions to build anywhere, not just in your region.

Setting up a region requires you to use WorldEdit to expand the region from top to bottom, so:
1. Select point 1 and point 2
2. //expand vert
3. /rg define spawn
By default, users should not be able to build within WorldGuard regions.
