[Solved] Member list not showing
Our developer said the following is how the member list issue was resolved: copied the current versions members.php over our modified version after backing it up and that seems to have fixed the problem. You might have to force a refresh or flush your cache if it’s still not working.

Then read the doc for permission issues (scroll to Member Information):
