Our website is live and the Authorize.net payment module is not working (we were unable to have an adequate dev environment!). But the Authorize.net module doesn't seem to be creating any error logs? Their tech support said to start there but i cannot find. nothing is being put in the main log file

Where are they suppose to be?

I noticed that in the PayPal has it's own log folder in the include/modules./payments/paypal

and Authorize.net did not. So i created one manually, but nothing is being put there
