I know how to install patches via shell, but this supee 7405 is giving me a problem.
The only error I get is checking file app/code/core/Mage/Checkout/controllers/CartController.php Hunk #2 FAILED at 472. 1 out of 2 hunks FAILED
I tried uploading the patched file, and then running the patch to update the rest of the files, but it still does not work..
No one else seems to have this issue with this file. All previous patches are applied
