Why is my Members Database blank? Follow
The full Member Database is only displayed after selecting SEARCH:
The default setting for the member database view is set to 'All' so if you click 'Search' you will see all records on the site's database although they may not have a Member of Website role.
To view the member database, administrators can filter search criteria via the Advanced Filter before clicking the Search button as this can allow you to find a more specific role/member.
