Magento blank sales order view page after SUPEE 7405 patch

If you applied the SUPEE 7405 patch or upgraded to Magento and suddenly you found out that your sales order pages are blank, then here’s a quick fix. Just copy app/code/core/Mage/Adminhtml/Helper/Sales.php to app/code/local/Mage/Adminhtml/Helper/Sales.php, then open it. Find $links = []; then replace it with $links = array(); then save it.

Clear your cache and check your sales order view page. It’s now fixed. This is currently a bug for PHP 5.4 and below, so another fix is just upgrade your PHP version to 5.4 and above to resolve this issue fast.


  1. Hi,

    I am facing the same problem here! I looked in “app/code/local/ “for a “Mage” folder, but I can not find it! I have: Aitoc, Am, Custom and Meigee!
    Should I copy the whole “Mage” folder from app/code/core/Mage/Adminhtml/Helper/Sales.php to “app/code/local/ ” ?

    I would appreciate some help!


  2. Hi! I’m using magento but this issue still happens for many orders…
    at this magento version this fix already exists.
    my php is 5.5.35 and there is no errors at logs…
