ZenCart 1.38
Authorize.net AIM
GoDaddy Host (already talked to them to no avail)

I installed ZenCart a couple years ago and it has worked perfectly until around late March when it suddenly started throwing these two errors. (And the admin of zencart has never been even opened since 2 years ago, this shopping cart brings in VERY minimal amounts of orders)

Error 1: "WARNING: Security hash problem. Please contact store-owner immediately. Your order has not been fully authorized."

Error 2:"Communications Error - Please notify webmaster. - Your credit card could not be authorized for this reason. Please correct the information and try again or contact us for further assistance."

I have remade the Transaction ID and the MD5 Hash multiple times and made sure that they match. I am including the .log file of one of the failed transactions:

I have spoken with Authorize.net and GoDaddy and they are stumped. Can anyone help me? I'll do anything to get this fixed! I have been reading through threads and alll over the internet, but all threads either too old so the resolution info is outdated or some other aspect of the issue is different enough to be no help in the end. PLEASE HELP!
:frusty::frusty::frusty::frusty::frusty::frusty::frusty:

1. You are using GoDaddy. That's your first huge problem.

2. Turn off the GoDaddy-initiated CURL Proxy Status option in Admin->my store.

Then go ask go daddy why they ever used a dumb proxy in the first place.

Thats already been done, like i said, the shopping cart has been working for two years already and started throwing errors at the end of this past March. :(

Um ... with all due respect, if your logs are showing that you ARE using the CURL proxy, then you have NOT turned off the setting which uses it.

So, go back and do as I said in my prior post.

I had the same problem. Took you advice and went into Admin to change the cURL. The instructions read like if I used GoDaddy (which I do) I had to go through them. But I tried turning it off anyway, and it worked. Thanks. Bill
