I have updated the PATCH_SUPEE-11085_CE_220.127.116.11_v1-2019-02-28-05-21-55.sh with zero error. After I tried to pay with credit card showing the below.
Gateway error: The merchant login ID or password is invalid or the account is inactive.
I checked the gateway URL, Payment Update URL. Also, I tried the DPM method the same error occurred.
Now, The Authorized.net payment process not working on my site. Please help me to fix this.
