Transaction cannot be accepted error message with Authorize.net integrated form payments

Hello, 

I have our form integrated with Authorize.net and we keep getting this error.

"PCI Error during transaction"

We have the form setup on this page: 

https://www.baltimorecountydental.org/quick-registration.html

We have already generated a new transaction Key so we are not sure what is causing this. Any input would really help.

As I research on the error message, it seems to be occurred due to various reasons. The new transaction key should fix the issue. The issue might also occur when the time on the server is not synchronized. Please try checking the Transaction cut-off time and the Timezone setting in your Authorize.net account settings. You may also check with Authorize.net support to see if there is any issue with the account. 

Please get back to us if the issue still persists. We will be happy to assist you further.
