Shopify Bug Fixing: 12 questions answered.

The cleanest option is a Collaborator request (we send it, you approve it from Settings → Users and permissions) scoped to Themes and the relevant apps, no password sharing. A limited staff account also works. If you prefer, duplicate your theme and give us access to the copy only. We always work on a duplicate theme regardless, so your live storefront is never touched until you approve the fix.

Yes. App embed conflicts are one of the most common Shopify performance killers: two apps inject the same library, or a leftover app block keeps loading after the app was removed. We audit every embed in theme.liquid and your app embeds in Theme settings → App embeds, remove duplicates, defer the heavy scripts, and clean out orphaned blocks. See our dedicated Shopify app conflict bug fixing page.

Yes. Many apps leave behind orphaned theme code, snippets, app blocks, and lines injected into theme.liquid or product.liquid, that throw Liquid error: Could not find asset or break layout once the app is gone. We find every leftover reference the app added, remove it safely on a duplicate theme, and verify the affected pages render cleanly again.

Most single Shopify bugs are fixed for a flat $99 Quick Fix (about 4 hours at $25/hr), one well-defined issue like a Liquid error, a broken section, or a cart drawer that won’t open. A $499 Bug-Fix Sprint (~20h @ $25/hr) covers a batch of bugs or one gnarly root-cause such as an app-conflict slowdown or a checkout.liquid migration, with regression tests. Emergencies and ongoing cover are quoted as a custom retainer.

Yes, we never edit your published theme. We duplicate your live theme, reproduce the bug on the copy, fix and regression-test it there, then send you a preview link. Only after you approve do we publish the duplicate as the live theme. Your original stays in the theme library, so a one-click publish reverts everything instantly if anything looks off.

Yes. If the exact bug we fixed comes back under the same conditions, we re-fix it at no charge. We root-cause the real problem rather than patching the symptom, regression-test cart, checkout, search and product pages before publishing, and hand you a short write-up of what changed. This is the Shopify hub in a wider emergency e-commerce bug fixing service, for theme-specific work see Shopify theme & Liquid bug fixing.

A single, well-defined bug is typically reproduced, fixed and verified within 24-48 hours. On the emergency tier, store down or checkout broken, we start triage in under 4 hours and can roll your theme back immediately to stop the bleeding while we work the root cause. Larger batches go into a Bug-Fix Sprint with a scheduled timeline you approve upfront.

This is a JavaScript or AJAX failure. “Add to cart” that does nothing usually means the /cart/add.js request is failing, a console error is swallowing the click handler, or a stale cart bundle is out of sync after an app or theme update. We open the browser console, find the failing request or error, and patch the cart events so the drawer opens, quantities update, and the cart count refreshes correctly.

Almost certainly. Shopify has retired checkout.liquid, so legacy checkout edits, additional scripts and order.status customizations stop running. The fix is to migrate to Checkout Extensibility, UI extensions, Shopify Functions, web pixels and the new branding API. We audit what you relied on, rebuild it the supported way, and verify the checkout end-to-end. For a deep dive see our Shopify checkout bug fixing page.

Yes. Blank metafields or Liquid error: undefined on a connected field usually come from a wrong namespace/key, a type mismatch, or a dynamic source that won’t bind in the editor. We check the metafield definition, correct the metafields.namespace.key reference in Liquid, handle the type (list, rich text, reference) properly, and confirm the value renders on the storefront.

That’s usually a broken section reference or schema. Liquid error (sections/...): Could not find asset means a {% render %} points at a snippet or asset that was deleted or renamed. A section that vanishes in the theme editor often has invalid {% schema %} JSON that won’t save. We repair the asset paths, fix the schema JSON, and restore the section settings so it appears and saves normally.
