How to stop rendering errors being output in production

Question

Due to a server problem one of our production sites was unable to connect to the DB.

While it was unable to connect the site was outputting the error:

An exception has been thrown during the rendering of a template ("Craft can't connect to the database with the credentials in craft/config/db.php.") in "_layout" at line 10.

I'm a little concerned that a production site is outputting this kind of information, is there a way to stop these errors being output?

(The site is currently running Craft Pro 2.1.2561 with dev mode disabled.)

Thanks.

DB connection errors are the only case where Craft will output the full error even if Dev Mode is disabled, because 99.99% of the time those only occur when Craft is not yet installed, and it’s an extremely common issue people run into when installing Craft.

If you really want to prevent those errors from showing up on the front end, you can edit your index.php file so that it catches them, and displays something different:

<?php

// Path to your craft/ folder
$craftPath = '../craft';

// Do not edit below this line
$path = rtrim($craftPath, '/').'/app/index.php';

if (!is_file($path))
{
    exit('Could not find your craft/ folder. Please ensure that <strong><code>$craftPath</code></strong> is set correctly in '.__FILE__);
}

try
{
    require_once $path;
}
catch (Craft\DbConnectException $e)
{
    exit('An error occurred.');
}
