When you try to sort users's list by registration date (registered) you get an error like:
WordPress database error: [Unknown column 'registered' in 'order clause']
SELECT * FROM wp_users ORDER BY registered ASC LIMIT 0, 30
this is beacuse the column name is "user_registered" and not "registered"
I was getting this same issue. It was resolved after this latest update in the morning on 11/22. The problem now is that there is a unexpected T_STRING error popping up in users.php... Around line 308. I have looked for anything obvious that is in my skill level, but am not able to find the problem.
The T_STRING error has been discussed in

and it is a little disconcerting that this error is still in a build after being reported on the 16th. The same thing seems to plague .htaccess. Many changes have been proposed, but .htaccess does not seem to incorporate suggested fixes in current releases.
