New Role Restricted

I have an account that needs to be a Membership Manager (a user role on WordPress, courtesy of Paid Memberships Pro), so this person can check the memberships on the site. I added the add-on and made this happen, but, for some strange reason, it won’t let him access the back-end of the site (WP-admin).

It feels like a Theme My Login issue, but I’m not 100 percent sure about that. We use the TML Profiles add-on, and the settings are set up correctly. Once this account logs in, it takes him to the /dashboard page (which I never even knew existed, to be honest), and gives an “edit profile” and “log out” link while NOT providing a “wp-admin” link as it SHOULD for this type of account.

1. Where is this /dashboard page coming from? It’s not needed.
2. Why is the Membership Manager account restricted from the back-end of the site (wp-admin)? Thanks.

I’m basically just trying to figure out how to allow admin access for this Membrership Manager user account role, and I would also like to get rid of the /dashboard page (if possible), since it’s not needed whatsoever. Thanks.
