I just installed the membership plugin and when I have a list of a bunch of members who I granted various levels of access to as an admin. I do not with to allow people to pay to signup on my account so I didn't setup any subscriptions. However, when logged in as the site admin, I can no longer edit users. Every time I click the 'update' button, i'm taken to a blank page (http://sasitup.com/partners/wp-admin/user-edit.php). Any idea why this is happening?
