Hello,

What I usually do with similar CMS issues is:

• Enable PHP errors so that you could get more information

• Enable Debug mode for your PrestaShop

• Check your Apache error logs

If this still does not help, I usually add this to my index:

// Debug - Add this on top of your index.php file

ini_set('error_reporting', E_ERROR);
register_shutdown_function("fatal_handler");

function fatal_handler() {
    $error = error_get_last();
    echo("");
    print_r($error);
}

So let’s say that you are getting this in your /admin area, then you need to add this in your /admin/index.php file. In 99% of the cases, this would display the exact error that is causing the white page.

Regards,
Bobby
