non-admins can't chat?

Hey. I use permissions EX. I set my self to admin, and I could chat. But when I set my self to any other group... Such as.. mod. I cannot chat. Why is that?

permissions.yml:

And no, nothing is wrong with the permissions.yml. But maybe I have to put a node for them to talk? like... something.cantalk?

I dont know. If you would like a list of the plugins that I have, I can post them.

Thanks, please help!
