Under account settings in Manage Account for Profile there is a public Profile URL: setting.
This URL is inaccessible, and after a user updates this setting the member directory wants to direct to this profile url.
So 2 issues:
One is the member directory is pointing to the public profile URL only after the profile url is set by a user. Prior to being set it points to the page that was created to display profiles.
Second is the Public Profile Url page is not being displayed, resource is missing.
