How fast can you fix a Shopify Liquid error?

A single, well-defined Liquid bug, a Liquid error: undefined method, an Unknown tag syntax error, or a broken {% for %} loop, is typically reproduced, fixed and verified within 24-48 hours. If your theme is white-screening or a section has vanished from the live store, emergency triage starts in under 4 hours and we can roll the theme back immediately. Every fix is built on a duplicate theme and goes live only after you approve a preview.
