FYI, BP 1.5.1 WP 3.2.1 single-site Linux
I’m pretty experienced and I’m stumped, especially on the last part involving http://mywebsite.com/nonexistentpage and http://mywebsite.com/members-directory/admin/nonexistentpage
In the latter, I’ve placed prominent “edit profile” links on single member profiles, and if another logged in user clicks these links for which they obviously don’t have permission to access, I want them to get a consistent “Page Unavailable/Restricted” 404 page, the same as they’d get if they tried to access http://mywebsite.com/nonexistentpage
