Support PermissionsEx

[HeberonYT]

Good day.
I'm creating a server kauldron (KCauldron-1.7.10-1614.201-bundle, MyTown2-1.7.10-0.5.0b, MyPermissions-1.7.10-66-dev, MyEssentials-Core-1.7.10-1.18r-universal) and have your mod installed.
The error appears mytown2 commands (/t new, /town new), none works, an error appears on permissions.

I have the essentials and PermissionsEx plugin to manage my server. I've added nodes permissions to all groups but do not work, I dare say ignores them.
I also used the MyPermissions and added to the Default group nodes, but does not work.
