Blank Page on Submission

Hello, 

I have had users complain about a blank page on submission.   I adjusted the page so that it will redirect after submission, but when I tested the form (using Authorize.net Sandbox) the blank page still shows after submission.   Any ideas?

Thanks! 

Your thank you page URL is incorrect.

You can see from the screenshot that the URL starts with "https:// http://..."

It should be either

https://www.losagaves.net/thankyou/

or

http://www.losgaves.net/thankyou/

I returned it back to the default Thank You page, but now instead of a blank page, I get an error when I run the transactions in Sandbox for Authorize.net.   I checked and everything seems to be correct with Authorize.net.   Any ideas?

This error usually occurs when your Authorize.net settings are incorrect. You need to check them. It could also be that one of your keys has expired. So try generating a new key.
