This one is kind of weird, so here is a reproducer:
Result is you are logged out, and presented with the login screen again.
I think this may be because the next page button link for some reason is an ip address, rather than the proper URI (http://209.132.184.123/wp-admin/users.php?paged=2)
The issue here is definitely the url change. Because of the change in domain name from fedoramagazine.org to the IP address, the browser stops sending the cookies requires to maintain logged in state.
Since I hit this while fixing SSL, I'm picking this up.
This is now fixed by setting $_SERVER['HTTP_HOST'].
