Manage Forms - Add Field goes to homepage in 1.6.1

Just did an install of the full Form/Flex mods in ELGG 1.6.1 . I can add forms, but when I go to add a field it errors out and goes to the home page. The form is trying to post to the following url (which doesn't exist with the install):


This file, and /action/form/, do not exist. Did I miss part of the install directions? Is this URL being improperly formed? Any help is appreciated.
