When i installed richtemplates on windows, and ran the example, i had a lot of 404 errors returned for the .css and .js files. I ran the setup as outlined in the instructions.
The following solved the issue for me.
(i added this line to setup.py in example_project) RICHTEMPLATES_MEDIA_URL = '/site_media/'
(i changed this line in example_project) MEDIA_URL = '/site_media/'
