Fix common Shopify problems.

Likely causes

• Promotions built from several discounts whose combination settings were never tested together.
• Price-based or weight-based shipping rates that stop matching once a discount changes the cart.
• App and theme scripts that were tolerable at normal traffic running on every product page view.
• Inventory, fraud and support setups that assume a slow, steady order rate.

What to check first

• 01Build the cart combinations your campaign will actually create and take each one through a new checkout.
• 02Test checkout with an address from every market you sell to, after the discount is applied.
• 03Freeze theme and app changes before the sale and write down exactly what is installed.
• 04Decide who answers order-status questions, and what they can see, before the emails start.

Likely causes

• The combination settings on one of the discounts don't allow the other discount's class.
• Two product discounts are meant to apply to the same item, which Shopify reserves for Plus stores with reciprocal tags.
• The store still has checkout.liquid customisations, or the order comes through a channel where combinations don't apply.

What to check first

• 01Open every discount in the promotion and read its Combinations section side by side.
• 02Check whether the stack you want puts two product discounts on the same line item.
• 03Test the exact codes together in a new online store checkout, not a draft order.

Likely causes

• The edit was made on an unpublished theme or the wrong template.
• A market-specific override is preventing the default version from inheriting the update.
• Theme app extensions or custom app code are still controlling part of the output.

What to check first

• 01Confirm the theme you edited is the published theme.
• 02Check the template and market selector in the theme editor before assuming the change failed.
• 03Review recent app installs or app embed settings if the section behaves differently than expected.

Likely causes

• The app injects storefront code, app blocks, or scripts that conflict with theme output.
• An app embed is active globally even though the feature should only affect one template.
• Older theme customizations and new app code are both trying to control the same UI.

What to check first

• 01Audit apps that touch the storefront, cart, product page, or checkout-adjacent experience.
• 02Disable the relevant app embed or extension temporarily and compare behavior.
• 03Check whether the issue reproduces on a clean copy of the theme.

Likely causes

• The wrong product template is assigned to that product.
• Section settings, block visibility, or product availability rules are hiding part of the layout.
• Theme code or rich text content introduced malformed markup around the product section.

What to check first

• 01Compare the affected product template against a working product.
• 02Confirm the product is active and available to the Online Store sales channel.
• 03Check for recent code edits or copied HTML that could break the product section markup.

Likely causes

• The product is hidden from search through Unlisted status or the seo.hidden metafield.
• Search & Discovery settings or other search tooling are overriding default visibility.
• Recent bulk actions, store reactivation, or indexing delays are making search look broken.

What to check first

• 01Confirm the product is published to the Online Store and is not set to Unlisted.
• 02Check whether the seo.hidden metafield is set to 1 or Search & Discovery is hiding out-of-stock products.
• 03Allow for indexing delays after bulk updates, reactivation, or large catalog changes before assuming search logic is broken.

Likely causes

• The theme does not support storefront filtering or the filter display setting is turned off.
• The collection or search result set is too large for Shopify to display filters.
• A third-party search setup or theme customization is bypassing Shopify's native filter output.

What to check first

• 01Confirm the theme supports filtering and that the Product grid or Search results section has filtering enabled.
• 02Check whether the collection has more than 5,000 products or the result set exceeds Shopify's documented limits.
• 03Verify the storefront is using Shopify's native search and collection templates rather than a third-party search layer.

Likely causes

• The variant picker does not populate the product form's variant ID on initial load.
• Custom theme JavaScript clears or fails to update the hidden variant input.
• An app script interrupts the theme's option-change event or submits an unavailable variant.

What to check first

• 01Test a single-variant product and a multi-option product in a clean theme copy.
• 02Inspect the cart/add request and confirm it contains the selected variant ID.
• 03Disable storefront apps that replace selectors, bundles, swatches, or product forms.

Likely causes

• Traffic does not match the product: bot sessions, untargeted ads, or visitors from countries you cannot ship to.
• Checkout is blocked for the buyer: shipping unavailable, missing payment methods, or currency and price surprises.
• The product page does not earn trust: weak photos, unclear pricing, missing reviews, or slow mobile load.

What to check first

• 01Look at add-to-cart and reached-checkout rates, not just sessions, to see where the funnel breaks.
• 02Place a test order from the countries and devices your traffic comes from.
• 03Compare traffic sources: real search and referral visitors convert very differently from bot or broad social traffic.

Likely causes

• The block exists in the app but was not added to the checkout configuration itself.
• Display rules or permissions do not match the current checkout context.
• The checkout configuration or market-specific setup differs from the one being tested.

What to check first

• 01Verify the block is added in the checkout and accounts editor, not just created in the app.
• 02Re-check the display rules, target configuration, and any market-specific conditions.
• 03Validate using a realistic test checkout rather than a guessed scenario.

Likely causes

• The stack relies on multiple apps that treat subscriptions, returns, and loyalty as separate systems.
• Customer state and order state are being updated in one tool but not reflected downstream.
• The merchant workflow has grown past what app defaults can coordinate safely.

What to check first

• 01Map which app owns subscription contracts, returns, store credit, and loyalty logic.
• 02Identify where customer support is compensating manually for tool gaps.
• 03Check whether key events are synchronized through native integrations, Flow, or custom logic at all.

Likely causes

• The cart does not meet the discount's product, collection, customer, or minimum-spend conditions.
• The discount cannot combine with another code already present in checkout.
• The merchant is testing through a draft-order or checkout setup where some discount types are limited or disabled.

What to check first

• 01Review the discount's active dates, entitlements, minimum requirements, and customer eligibility.
• 02Check whether another code, automatic discount, or checkout context is overriding the expected outcome.
• 03If testing draft orders, confirm customer-applied discounts are enabled and account for Shopify's draft-order discount limitations.

Likely causes

• The buyer's country is not in an active market or is not eligible for that payment method.
• The method is not actually activated in Shopify Payments, or conflicting additional gateways are blocking activation.
• The method has extra eligibility requirements such as country, store setup, or order-volume thresholds.

What to check first

• 01Confirm the relevant market is active and that the test buyer is checking out from a supported country.
• 02Verify the payment method is enabled in Shopify Payments and that conflicting additional gateways have been removed if required.
• 03Review method-specific eligibility requirements before treating the issue as a checkout bug.

Likely causes

• The customer is not signed in through new customer accounts or Shop Pay.
• Store credit is disabled in Customer accounts, or the balance is in a different checkout currency.
• The order is a draft, edited, recurring subscription, B2B, or unsupported sales-channel transaction.

What to check first

• 01Confirm store credit is enabled and the customer is signed in through new customer accounts.
• 02Match the credit currency to the checkout currency and test a normal Online Store order.
• 03Check whether the order type or channel is excluded by Shopify's store-credit restrictions.

Likely causes

• The store uses a gateway that cannot process Shopify Markets local-currency payments.
• A display-only currency app changes storefront prices but cannot control checkout currency.
• The selected market, customer country, or locale-aware cart state is inconsistent.

What to check first

• 01Confirm Shopify Payments or Adyen is the primary gateway for true multi-currency checkout.
• 02Test the intended market using its country selector, shipping address, and a compatible payment method.
• 03Remove display-only currency apps from the test and inspect locale-aware cart requests.

Likely causes

• A product in the cart sits in a shipping profile with no rate for the buyer's zone, or isn't set as a physical product.
• The location holding the stock is inactive, can't fulfil online orders, or has no rates for that zone.
• The cart's weight or discounted value falls outside every rate tier, or carrier-calculated rates can't price the package.
• The buyer's country isn't in a market, or the market has no shipping rates.

What to check first

• 01Recreate the exact failing cart and address in a new checkout, never an old abandoned one.
• 02Check the shipping profile, zone and rates for each product in that cart.
• 03Check the fulfilling location is active and set to fulfil online orders.
• 04Compare the cart's weight and discounted total against every rate tier.

Likely causes

• Inventory is available in a location that cannot fulfill the buyer's shipping zone.
• Fulfillable inventory settings and shipping-zone logic are not aligned.
• Market-specific inventory behavior is exposing edge cases across locations.

What to check first

• 01Confirm which fulfillment location actually has stock for the buyer's market and shipping zone.
• 02Review fulfillable inventory settings and whether the store is relying on location rules that changed in 2025.
• 03Check whether the product is blocked only in specific markets or address scenarios.

Likely causes

• The market has an override, so updates from the default storefront are no longer inherited automatically.
• Translations are outdated or missing for recently changed content.
• The editor context is set to a market or language that does not match the content being reviewed.

What to check first

• 01Verify whether the affected section or block has a market override.
• 02Update untranslated or outdated content rather than assuming the theme failed.
• 03Check the market selector in the theme editor before editing or diagnosing further.

Likely causes

• Different templates are assigned across resources without a clear governance rule.
• A market-specific override changes visibility or ordering of sections.
• The team is editing one template while diagnosing a different one.

What to check first

• 01Compare template assignments across affected products or collections.
• 02Review whether the issue exists only in one market, one language, or one product type.
• 03Standardize template ownership before making more one-off fixes.

Likely causes

• Metafield definitions exist, but the team is not using the bulk editor effectively.
• The catalog has outgrown ad hoc admin workflows and now needs stronger data structure.
• Variant and product data are split across tools with no single reliable editing pattern.

What to check first

• 01Audit which fields can be managed directly in Shopify's bulk editor before defaulting to CSV.
• 02Clean up metafield definitions and naming so the team can find the right fields quickly.
• 03Separate bulk operational edits from one-off merchandising edits.

Likely causes

• The store has accumulated too many half-connected apps solving narrow problems.
• Operational rules live in people and process rather than structured admin logic.
• The business is using Shopify beyond the point where default workflows stay efficient.

What to check first

• 01List the recurring manual tasks the team repeats each week inside the admin.
• 02Identify which workflows depend on exports, duplicate entry, or cross-tool checks.
• 03Prioritize the workflows that hurt margin, launch speed, or support load first.

Likely causes

• A browser extension, stale cookies, or a cached redirect is breaking the admin session.
• The staff account lacks permission for the section that appears broken.
• Analytics or reports are missing data because of tracking, app, or date-range issues rather than an admin outage.

What to check first

• 01Check status.shopify.com and try the admin in an incognito window with extensions disabled.
• 02Confirm the staff account has permission for orders, analytics, or the app that fails to open.
• 03Compare the Orders list against the Analytics overview for the same date range before assuming data is lost.

Likely causes

• The branded sender domain is missing Shopify's DKIM/SPF CNAME records or has no valid DMARC record.
• Multiple or overly strict DMARC records cause authentication checks to fail.
• The notification template, recipient address, or an email-provider filter is responsible rather than order creation.

What to check first

• 01Send a test notification and confirm the affected order contains the correct customer email.
• 02Check the sender email status and authenticate the domain through Shopify.
• 03Verify DKIM/SPF CNAME records and exactly one valid DMARC TXT record at the domain host.
