New Post: How to enable or integrate Authorize.Net For DNN 7

Geoff,
I'm running into this same issue. This is what I've figured out so far:

• Paypal and Authorize.net work perfectly on their own and return payment success or fail correctly
  

When Paypal and Authorize.net are enabled together:

• Paypal works perfectly and returns payment/success fail correctly
• Authorize.net will not return success/fail, it will return to the blank page I setup, but will not give the pass or fail message and the order shows "Waiting for bank"
  

Any ideas? It looks like I'm running into the same issue as maniazi83 above. Thanks!
