Top 10 troubleshooting scenarios
- Widget not showing on product page — app embed disabled or personalizer not attached to this product

- Live preview not updating — mobile browser cache, or CSP blocking Google Fonts
- Font not loading — CSP

Frequently asked questions
Why isn't my product personalizer widget showing on the product page?
Most common: app embed disabled in your theme. Fix: Online Store → Themes → Customize → App embeds → toggle ON. Or personalizer not attached to this specific product.
How do I fix Print It My Way widget not showing?
6-step check: (1) app embed enabled, (2) personalizer attached to this product, (3) using default product template, (4) Shopify 2.0 theme, (5) no theme code blocking, (6) hard-refresh browser (Ctrl+Shift+R).
Why is my personalizer photo upload failing?
5 common causes: (1) DPI below 100 (hard block), (2) file size above 10 MB, (3) unsupported format (HEIC not enabled), (4) slow customer connection timeout, (5) app cloud storage temporary issue.
Why isn't the cart showing my personalization properties?
5 causes: (1) property name starts with underscore (intentionally hidden), (2) cart-drawer.liquid missing properties loop, (3) cart-drawer JS overrides template, (4) property added after add-to-cart, (5) wrong input syntax (must be properties[Field Name]).
Why isn't my order showing personalization data?
Order missing properties means they weren't captured at add-to-cart. Widget not rendered on product page → nothing to capture. Fix widget first (see widget-not-showing article).
Why is my live preview not updating in real time?
Mobile browser cache, or CSP blocking Google Fonts CDN. Hard-refresh; check DevTools Network for red 4xx font requests.
Why is my custom font not loading in personalizer?
CSP (Content Security Policy) blocking Google Fonts. Add https://fonts.gstatic.com to font-src. Or ad blocker / privacy extension blocking Google Fonts.
Why isn't my Cart Transform fee showing at checkout?
Shopify Plus check (Cart Transform is Plus-native). Non-Plus uses app-side mechanism — verify Print It My Way's fee-display setting is enabled. Or discount code stripping the fee.
Why isn't my POD partner receiving personalization data?
Line-item properties should flow via Shopify's Order API. Contact POD partner support with order number. Their integration may need re-syncing. Print It My Way's admin queue flags any rejected orders.
Why is my iPhone HEIC photo rotated wrong?
EXIF orientation not preserved. Print It My Way auto-handles HEIC EXIF. If still wrong, ask customer to re-save the HEIC (iMessage to themselves works).
Why is my personalizer slow on mobile?
Check Core Web Vitals (Lighthouse). Uninstall conflicting apps. Print It My Way is <50 KB gzipped — if slow, other apps are the cause.
