Can't get CKEditor plugins to work in django

I am trying to get the CKEditor plugin, codesnippet, to work in the django admin but am unable to. CKEditor works if I don't define any CKEDIT_CONFIGS in my settings.py. It also works if take out the "extraPlugins" line (and it successfully will adjust the height and width as defined in the CKEDITOR_CONFIGS section).

I installed CKEditor using the instructions here: https://github.com/shaunsephton/django-ckeditor

CKeditor is located in /static/ckeditor and codesnippet is in /static/ckeditor/plugins/

In my settings.py
CKEDITOR_UPLOAD_PATH = 'uploads/'
CKEDITOR_JQUERY_URL = '/static/js/jquery-2.1.1.min.js'
CKEDITOR_CONFIGS = {
       'default': {
           'toolbar': 'Full',
           'height': 400,
           'width': 900,
           'removePlugins': 'stylesheetparser',
           'extraPlugins': 'codesnippet',
       },
   }

My admin.py
from django.contrib import admin
from blog.models import Article, Category
from django.utils import text
from django import forms
from ckeditor.widgets import CKEditorWidget

class ArticleAdminForm(forms.ModelForm):
    body = forms.CharField(widget=CKEditorWidget())
    class Meta:
        model = Article

I have also tried using just 'plugins' instead of 'extraPlugins' (although this not recomended), but get the same result (which is it breaks CKEditor and the filed doesn't display at all in the admin).

Thanks in advance for your help!
