My site is CommonThief.com and I just tried to setup the affiliate plugin and I noticed my users once signed up can not access anything because all links point to the admin page.
I had my friend sign up, and when he clicks dashboard it brings him nowhere. I look at the link more carefully, and it's pointing to /wp-admin/dashboard (or something similar..)
Same if you go to the affiliate page under My account, you are asked to fill in your profile. the link tries to send you tot he admin page.
