Hi, I’m a Shopify developer experienced with Prestige theme debugging and mobile cart issues. I’ll trace the JavaScript/AJAX and Liquid logic causing the SyntaxError and lagging cart state, fix variant handling, and ensure add/remove/update actions work reliably on iOS and Android. You’ll get a stable patch plus a brief report on the root cause and future-proofing steps. lets discuss in chat as I have some queries to ask regarding the project to proceed further.

Hi Dominik, To address the Shopify Cart Bug Fix project, I will thoroughly analyze the Prestige theme code to identify the root cause of the cart misbehavior on mobile devices. By debugging the Shopify Liquid, JavaScript, and AJAX carts, I will ensure seamless functionality for adding products, updating quantities, and resolving the SyntaxError issue.

Hello, I specialize in debugging and optimizing Shopify themes, especially complex AJAX cart and variant scripts like in Prestige. From your description, it sounds like the cart’s JavaScript is caching outdated product data or misfiring the fetch/update cycle on mobile. I’ll inspect the Liquid templates and JS listeners handling variant changes, isolate where the cart sync breaks, and implement a mobile-safe AJAX patch. Once fixed, I’ll document every change with notes to preserve compatibility during future theme updates. You’ll get stable cart behavior across iOS and Android with reliable product data flow. Thanks- Nitish Bhardwaj

Hi! I’m Ben Jackson from Jetjams Technologies. I can quickly diagnose and fix your Prestige (Shopify) mobile cart issues so add-to-cart, variant switching, quantity updates, and removals work perfectly on iOS + Android. What I’ll do • Debug the JS/AJAX cart flow (cart drawer/cart page) and reproduce the “one item behind” behavior • Track the SyntaxError on image swipe/variant change (invalid URL/pattern, malformed request, or event timing) • Patch Liquid + JavaScript to ensure the cart always references the current variant/product • Verify across mobile browsers (Safari iOS, Chrome Android) and test add/remove/update flows Deliverables • Stable fix in theme code (with notes so it survives future updates) • Short report: root cause, files changed, and update-safe guidance Lowest reasonable price (EUR): €180 for diagnosis + complete fix (typical same-day/next-day depending on access). We are so much grateful to serve you. Ben Jackson — Jetjams Technologies

@chuka8

Hello! I understand how frustrating cart issues can be on mobile, especially when it impacts the shopping experience. I have extensive experience debugging and customizing Shopify themes, including the Prestige theme, and I can help resolve these mobile cart problems efficiently. My plan is to: 1. Review your existing theme code, focusing on the JavaScript responsible for AJAX cart updates and variant handling. 2. Identify the root cause of the “SyntaxError” and why the cart is showing outdated items—likely a conflict or timing issue in the scripts. 3. Implement a fix to ensure the cart updates reliably on mobile devices, with proper synchronization and error handling. 4. Provide a brief report detailing what was fixed and recommendations to maintain stability after theme updates. I can start immediately and aim for a quick turnaround so your customers can shop smoothly again. Please share access to your store or a staging link if available, and I’ll get to work right away. Looking forward to helping you fix this seamlessly!

Hello, I hope you are doing well. -> Previous Work: I’ve delivered reliable Shopify back-end and front-end fixes for stores using the Prestige theme and other responsive templates. My recent work focused on stabilizing AJAX cart flows, removing race conditions, and ensuring cross-device consistency for mobile carts in iOS and Android environments. I bring strong expertise in Shopify Liquid, JavaScript, and AJAX-driven cart logic to produce production-ready, maintainable fixes. -> Development Plan: 1) Reproduce the mobile cart mis-sync and the SyntaxError on variant changes in a controlled dev store and trace through the Prestige theme’s JS and AJAX cart logic. 2) Identify race conditions or off-by-one state updates when items are added/removed/variants changed, including any event debounces, caching, or DOM updates that cause the cart to show the previous item. 3) Implement targeted patches in Liquid templates and JS modules to ensure the cart reflects the current selection, plus robust error handling for variant changes (eliminating the SyntaxError). 4) Add defensive checks, unit-like sanity tests, and lightweight logging to help monitor cart state after updates. 5) Provide a concise report detailing what was fixed and steps to keep the cart stable after theme updates, plus guidance for future QA. -> Schedule: - Day 1-2: Diagnosis and patch implementation on core cart flow. - Day 3: Cross-device testing (iOS/Android), refinements, and regression checks. - Day 4: Deliverab
