debugger just got up and left

so i started work on my site today and the debug toolbar is just not showing - having not changed a thing from the previous night.

To confirm, web/index.php is still as original:


// comment out the following two lines when deployed to production

defined('YII_DEBUG') or define('YII_DEBUG', true);

defined('YII_ENV') or define('YII_ENV', 'dev');

require(__DIR__ . '/../vendor/autoload.php');

require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php');

$config = require(__DIR__ . '/../config/web.php');

(new yii\web\Application($config))->run();

Any other reason why it wouldnt show ?

Just to prove - here is the bottom of my page:

Did you modify your configuration?
