I am trying to process payments on my website, but am getting an error when submitting payment. It gives me the:
Warning: Unrecognized response from AuthorizeNet: ErrorE00003Data at the root level is invalid. Line 1, position 1
All my research points to an XML or JSON issues, but I can't find where that file originates. Any help would be appreciated. Here is my site:

Please try to submit a payment for any product and you will see the error code pop up. I have searched my files for "createTransactionRequest" but can't find anything.
Thanks!
