How do you prevent debug messages from displaying?

When I set my debug mode to Production...and a recoverable error occurs within the code, CakePHP will output the error details in the UI. How do I prevent this from displaying?

...debug config setting:

Configure::write('debug', 0);

...sample code to cause an error (within a controller action):

 $myError = $something['NullExceptionGoes']['HERE'];

...this causes a cake-debug block to be added to the view (just below the beginning body tag):

error details will be output...i do not want users to see this info...i want to p开发者_如何学Crevent this block from being displayed

<pre class="cake-debug">
    <a onclick="document.getElementById('cakeErr1-trace').style.display = (document.getElementById('cakeErr1-trace').style.display == 'none' ? '' : 'none');" href="javascript:void(0);"><b>Notice</b> (8)</a>
    : Undefined variable: something [<b>APP/controllers/home_controller.php</b>, line <b>12</b>]
    <div style="display: none;" class="cake-stack-trace" id="cakeErr1-trace">
        <a onclick="document.getElementById('cakeErr1-code').style.display = (document.getElementById('cakeErr1-code').style.display == 'none' ? '' : 'none')" href="javascript:void(0);">Code</a> | <a onclick="document.getElementById('cakeErr1-context').style.display = (document.getElementById('cakeErr1-context').style.display == 'none' ?

You are probably overriding debug output in your controller method.

Verify that:

Configure::write('debug', x);

is not in your controller as well (where x = 1 or 2).
