ZenCart Ecommerce Store: Web Page Redirect Loop Error, CEON advshipper
During verifying some upgrades I had made to a ZenCart store I ran into some issues during checkout with a couple accounts. The issue was that my browser would get caught in a redirect loop after I added contents to my shopping cart and then attempted to checkout. At first I thought the issue may be with the checkout_process.php file as it was one of the files I had upgraded recently though after a more troubleshooting I determined this was not the case.
