Blank page CDiscount

Cases you may see:

• after install, click Configure → blank page;
• click a module tab → blank page or truncated PrestaShop back office.

This usually hides a PHP error. To display it, temporarily enable PrestaShop debug mode:

1. If the back office still responds: Advanced Parameters → Performance → Debug mode → Yes, then save.
2. Otherwise (or if that is not enough): edit config/defines.inc.php and set _PS_MODE_DEV_ to true:

define('_PS_MODE_DEV_', true);

PrestaShop docs: Configuration / displaying errors

Reload the page, copy the full error message (or a screenshot), then disable debug mode immediately.

Send the message to our support (Business Care / chat).
