Well you can enable debug on a live site, But it is best to do it the following way.

if ($_SERVER['REMOTE_ADDR'] == 'xx.xxx.xx.xxx') {
    $config['Misc']['debug'] = true;
} else {
    $config['Misc']['debug'] = false;
}

Replace xx.xxx.xx.xxx with your ip address and the debug information will show only for you.

This will help to debug errors on your live site.
