Security Patch SUPEE-7405 - Possible Problems? (15 answers)

Closed 4 years ago.

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.

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

Answer 1

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!!
