Massively frustrating Internal Server Error upon checkout

WebDev22 · November 29, 2012

When customers complete their order, they are taken to the checkout_process.php, with an Internal Server Error message. Here's the link to the page: http://bit.ly/112XMQU, but the error only seems to occur when completing an order. I checked permissions on all the root-level files and have them set to 0644. I also disabled all advanced email settings in admin, in case it was related to that.

The site is hosted at GoDaddy and it's my understanding there might have been some sort of server configuration change a few months back. Any ideas what could be causing this? Do I need to maybe remove all spacing before and after opening and closing php tags?

Thanks for any help. I've included the code for the checkout_process.php page below:

Have you tried enabling the COD payment method to determine if it is the Authorize.net payment module that is causing the failure ? I would assume if the COD method works, then the error is limited to the authorize.net payment module. Also, you are running an out-dated version of osCommerce and I BELIEVE there are newer authorize.net payment modules available.
