Issue with new players on my server

[Brandon Reddish]

Hi all! Long time lurker, first time poster.

Having an issue on my server. New people cannot do .. well, anything. They can't break blocks, they can't place blocks, they can't hit animals, and mobs don't respond to them. This is all areas, not just spawn. I'm assuming it's a permission issue with one of my plugins, but I cannot seem to be able to narrow down which one is causing the issue.

Tekkit Classic 3.1.2

Plugins:

CCPlugin

ChatManager

Enjin Minecraft

Modifyworld

PermissionsEx

SimpleClans

WorldEdit

WorldGuard

mcMMO

I set the permissions to "*" in my PermissionsEx folder for default users, but that doesn't seem to change anything.

Anything help would be great. Please let me know if you need any information from me. Thanks!
