I just upgraded our DNN to 7.1. One thing I noticed is when you go to Admin > Security Roles > edit Security Roles, click on Manage Users in this Role, and then click on Close. The page will return Server Error 404 - File or directory not found. It is working fine on our production DNN, which is still version 7.0.6. So I'm just wondering if this is a bug or something wrong with our dev end. Thanks.
