How to Troubleshoot CS-Cart Checkout That Loops Back to the Cart

11/10/2026

A checkout loop can occur when shipping, payment, inventory, session, or validation state cannot advance.

Checks to make

Reproduce with a controlled cart and note the step that resets. Inspect validation messages, session cookies, shipping and payment availability, and recent add-on changes. Review logs without exposing customer payment data and test one configuration change at a time.

When to get help

CS-Cart support can trace checkout state and validation flow. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
