Blank page in admin area

If in your backend at one of the Smart Slider’s pages you get a blank page, you can probably make your website to write out the error if you open up this file:

app\code\community\Nextend\SmartSlider2\controllers\Adminhtml\SmartsliderController.php

And put this code right under the <?php part:

error_reporting(E_ALL); ini_set('display_errors',1);
