Problem: Admin blank page with no errors even while the debug mode is on.

Solution: Frankly i cant tell why it behaved odd on this version but the option to debug or not to debug is an option in Prestsahop that can be used at any time. Unfortunately there were no errors displayed on the admin link to hep but a solution came from Prestashop forum.

Simply change the debug mode in /config/ from ‘true’ to ‘false’

/* Debug only */
if (!defined(‘_PS_MODE_DEV_’)) {
define(‘_PS_MODE_DEV_’, false);
/* Compatibility warning */
if (_PS_MODE_DEV_ === true) {
@ini_set(‘display_errors’, ‘off’);
@error_reporting(E_ALL | E_STRICT);
define(‘_PS_DEBUG_SQL_’, false);
} else {
@ini_set(‘display_errors’, ‘off’);
define(‘_PS_DEBUG_SQL_’, false);

define(‘_PS_DEBUG_PROFILING_’, false);
define(‘_PS_MODE_DEMO_’, false);

Hope this works?
