How do I turn off maintenance mode? Does anyone know how to turn off maintenance mode for brainfx?  I tried http://www.website.com/?q=user/login but that gives me a blank page (no html source or anything).  I tried the following query.

UPDATE `variable` SET `value`='0' WHERE 'name' = 'maintenance_mode';


It didn't affect any records.  

I tried to find a $conf['maintenance_mode'] variable in the project, but it doesn't exist. Adding that $conf['maintenance_mode'] = false; in setting.php didn't do anything either.

Using Drush, you can run drush vset maintenance_mode 0 to disable the maintenance mode on a Drupal 7 site.
