I can't get past the login panel on my site

I’ve added the [membershiplogin] shortcode to the homepage of my site. However, when I enter any user details I can’t access any of the page content, other than what is made visible to non-subscribed visitors. I can access the Dashboard and profile settings, but none of the actual content that should be available to this users level.

I’ve set and assigned levels and subscriptions as per your demo videos, but I just can’t make it work.

I’m running the site of a WP multisite, could this be causing the problems?
