This question already has an answer here:

After a couple of days that the patch supee-7405 was released I've decided to install the it.

I did a backup of my website because I could see there were a lot of files to modify and I suspected that something could be wrong and yes, something has been wrong.

When I am on the admin panel and I go to sales>orders it looks like everything is ok. But when I try to access to any of those orders I can't see the information of that order.

enter image description here

Does this have a solution or I should go back to my backup?

  • Interesting, you should be getting an error in your webserver logs and/or in your magento logs, could you post it here please ? – Raphael at Digital Pianism Feb 26 '16 at 10:51
  • Where can I find this? I know I can get error information when Magento gives error and you can't even access to the website on var/report. But where can I see such non-critical error information? – danibg Feb 26 '16 at 11:01
  • Depends on your server, var/log for Magento logs. To get your server error logs, you can do it via cPanel or an other server admin web access. If you have full access to your server via SSH you can find them in the /var/log folder – Raphael at Digital Pianism Feb 26 '16 at 11:02
  • Ok, I found it: var/log/system.log. The problem is the file weights 20GB and it would take a lot of time to download it. – danibg Feb 26 '16 at 11:06
  • Wow, I suggest you delete it and reaccess the order page. It will update the file with only the error you're interested in – Raphael at Digital Pianism Feb 26 '16 at 11:08

The solution to this is just installing the 1.1 version which can be found here. I'm not sure if this happens to everyone or only when you install the patch by overwriting patch files through ftp that is how I did it.

You should to go to app/core/Mage/Adminhtml/Helper/Sales.php then look for some code like this $links = []; and change to $links = array(); for me it is at line 124. Or you can search inside Sales.php file using ctrl+f command , and try to search for [] then change to array(). Hope it helps you. Thanks!!
