Use your browser to go to your_site.com/extras/curltester.php?authnet=1 and look at the page that it creates. Then give that URL to your hosting company because they'll need it in order to see the error message (without having to create transactions on your website). They can use that same URL to test their fix too.
Thank you, Dr. Byte! I just attempted to view that page myself before contacting the web host and I got this 404 error message: Not Found

The requested URL /extras/curltester.php was not found on this server. Is this a sign of another problem or is this what I should expect to see? I want to be sure before giving this to the web host as a means for trouble-shooting. Thanks!
