I've just noticed I'm seeing a strange number in my number of users in /wp-admin/users.php
It reports I have:
All (17) | Administrator (16) | Contributor (1)
but the list only shows 1 contributor and 3 administrators (I created all these user accounts, so there's no security breach there)
I've checked the database, and there are only 4 users in the [prefix]_users table.
Where do these numbers come from, and why might they be miscounting?
