Register permissions from YML

So I am trying to register permissions from a YML file, and so far not going to well. I can't seem to find much documentation, or how the Essentials team does it with their multiplehomes shenanigans.

Any help would be appreciated, here is the error I get:

Code:

03:21:37 [SEVERE] There was a problem registering permissions for multiple plots

And here is the code behind it so far:
