I SSH the patch - Authorize.net Direct Post Signature Key patch -
PATCH_SUPEE-11085_CE_220.127.116.11_v1-2019-02-28-05-21-55.sh and it was successful then following the directions here
I entered my security key and saved it successfully. I then went to make a purchase and when I select "Place Order" at the end all that happens is that the page flashes. I don't get any errors. I don't know whats wrong. I contacted Authorize.net and they said to contact Magento.
Authorize.net Direct Post transaction key update (MD5 to SHA-512)
I am already using Authorize.net Do I have to do anything? I am not using Authorize.net Direct Post in Magento’s backend. The patch is misleading making me think I have to switch over but I read if you are using Authorize.net you don't have to switch to Authorize.net Direct Post in Magento's backend. Can someone give some clarity to this?
