You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'id` = '5'' at line 1
UPDATE `users` SET `last_login` = 1270844033 WHERE ` IS NULL AND `id` = '5'
I had the login set to remember, and was away for a few hours. When I tried to get back to the login screen, this is what I got. Once I restarted Firefox it worked... so it seems to be something weird in the sessions, and the "_extra_where".
