How can I display errors when I have a blank page?

• Use your FTP client, go to your web server’s FTP, and open the file defines.inc.php, which is in the /config folder. There’s a bunch of texts, then you will see as follows:

• Change that second line: replace “false” with “true” (without quotes). It will appear:

/* Debug only */

define(‘_PS_MODE_DEV_’, true);
if(_PS_MODE_DEV_)
