One of the most annoying things that can happen in a CS Cart installation, is a blank screen, without any errors.

First you check the error_log but it is empty, then you check the server logs but you find nothing. So what can you do to troubleshoot a CS Cart white page?

It is pretty simple, open config.local.php and below this line

if ( !defined('AREA') ) { die('Access denied'); }

add this line

define('DEVELOPMENT', true);

Now the error will be displayed and you can see what is causing the blank screen.

One of the most common causes for a white page is database connection. Double check your settings before making anything else.
