Solved Modify world - Players can't place/break blocks.

Hey guys. I recently got a server and now I have a problem.
I am having problems with players in the "Members" group, not being able to break/place blocks.

I am using pex and essentials, so I am suspecting ModifyWorld is the problem. I am relatively new to Essenials-anti build, which could also be the problem.
Here is my..
Pex perm file. http://pastebin.com/n0zvUAmp
Modify world config http://pastebin.com/MWEeaUDN

I have run many servers in the past, and never had a problem. So I am experienced.
Members are not in spawn area, so its not spawn protection that is stopping them.

Here is all my plugins:
BukkitCompat, multiverse-core, Pex, essentials, chatmanager, essentials protect, essentialspawn, multiverse-portals, multiverse- inventories, setrankPEX, essentialschat, modifyworld, and essentials-antibuild.

Thanks guys.

 

if you want to use essentialsantibuild.jar, give essentials.build node, if not, move out essentialsantibuild.jar

 

Thanks!
