Blank page after upgrade

Error:

– After upgrading the Smart Slider, blank page, where the sliders were, and/or the Smart Slider’s backend has a blank page.

This could happen for many reasons, one is, that if you only upgraded the Smart Slider, but didn’t upgraded the Nextend plugin. If this wouldn’t be the problem, you can try to make your website write out the error by putting this code in the beginning of your wp-config.php file:

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

And if that doesn’t show anything, then write this code in the beginning of these files instead (try them out in this order, and these are for the backend):

\wp-content\plugins\nextend-smart-slider2-full\admin.php

\wp-admin\includes\screen.php

\wp-admin\admin.php
