We saw a blank page at /checkout/* after applying SUPEE-10752 and compiling


Triggering conditions:applying SUPEE-10752 + enable compiler + login as a customer, then visit /checkout/*

Just to clarify: With deactivated compiler all things went well, with activated compiler we only could see a blank cart page when logged in without any log entries (even after activating all possible logs and developer mode).

  • Did you get any solution ?

I Have got same issue some times ago and found a work around Here

You need to copy from:




Search function :

public function getPasswordTimestamp($customerId)
    /** @var $customer Mage_Customer_Model_Customer */
    $customer = Mage::getModel('customer/customer')
    $passwordCreatedAt = $customer->getPasswordCreatedAt();

    return is_null($passwordCreatedAt) ? $customer->getCreatedAtTimestamp() : $passwordCreatedAt;

Replace it with:

public function getPasswordTimestamp($customerId)
    $resource = Mage::getSingleton('core/resource'); $resource = Mage::getSingleton('core/resource');
    $readConnection = $resource->getConnection('core_read');
    $query = 'SELECT * FROM ' . $resource->getTableName('customer_entity').' WHERE `entity_id` = '.$customerId; 
    $results = $readConnection->fetchAll($query);

    $result=$results[0]; $result=$results[0]; 
    $date_created = Varien_Date::toTimestamp($result['created_at']); 
    return $date_created;

After that you need to recompile and flush cache:

Note: in Blog , They explain due to patch, customer load is failed and we manually need to get created_at of current user.


Still investing this but by enabling the scream option on xdebug, I was able to determine that the problem is the Zend_Date class is loaded twice when compilation is enabled and the load function is called on a customer, hence the error.

On the checkout pages specifically, it is included in the __checkout.php file and the Zend_Date.php file is also included.

The replacement code above, while it allows for compilation to proceed by not loading the customer model, does not account for the new password_created_at attribute created by this patch.

Side Note: The Varien_Autoload class has the suppression operator (@) which prevents errors from being logged or displayed(!!), hence the blank page/lack of logging.


  • You are very professional, tell me if have a good solution, thanks
