There may be several reasons if you can't access your dashboard after logging in.
A) You have logged in on support.betternow.org (this site), but you need to log in from your own white-label site.
B) You have logged in with a user that does not have admin rights. You can check what email you have logged in with by going to your profile page. If this is your personal email, log out and log in with your work email.
C) You don't have access to the administration section. Press the 'Administration' link as in the screen below. If you don't see this, then you are logged in as a user without any administration rights.
