[SOLVED] Can't leave maintenance mode

Hello,

I have placed my gallery in maintenance mode by checking the option in Site Manager > Maintenance > maintenance .
Now I didn't look at the location it was about to forward my maintenance page.

So my question is where I can disable the maintenance mode from the DB? Because in config.php has

$gallery->setConfig('mode.maintenance', false);

Gallery version : 2.3
PHP version : 5.3.14
Webserver : 2.2.22
Database : MySQL version 5.1.68-cll
Activated toolkits :NetPbm, GD, thumbnail manager
Operating system : Linux
Browser: FF 19
