BigCommerce Stencil主题结账页面翻译失效问题求助

Hey there, let’s walk through why your checkout page translations aren’t taking effect even after adding the optimized_checkout block to your en.json file. I’ve tackled similar Stencil theme translation quirks before, so here are the key steps to diagnose and fix this:

• Double-check your optimized_checkout JSON syntax
  JSON is super strict about structure—even a missing comma or mismatched quote can break the entire block. The snippet you shared ("optimized_checkout": { "address": { "address_l...") looks truncated, which is a red flag. Use a JSON validator (like the built-in checker in VS Code) to ensure the entire optimized_checkout object is properly nested and formatted. For reference, a correct structure should look like this:

  "optimized_checkout": {
    "address": {
      "address_line1": "Street Address",
      "address_line2": "Apartment, Suite, etc.",
      "city": "City"
    },
    "checkout": {
      "title": "Complete Your Purchase",
      "continue_to_payment": "Proceed to Payment"
    }
  }
  

• Confirm you’re editing the right locale file
  If you’re translating to a non-default language (e.g., Spanish), make sure you’re modifying the corresponding [lang].json file (like es.json) instead of just en.json. Also, verify the file is located in the theme’s lang/ directory—some themes might have nested language folders, so double-check the path.

• Flush caches and rebuild the theme
  Stencil loves to cache old language data. After updating your JSON file:

  1. If using the Stencil CLI, run stencil start to rebuild and reload the theme.
  2. If using the BigCommerce online theme editor, click Publish to push changes live.
  3. Clear your browser cache or test in incognito mode to avoid loading cached checkout assets.

• Check for BigCommerce backend overrides
  Your store’s backend settings might be overriding theme translations. Head to Store Setup > Languages, select your target language, and navigate to the Checkout & Account section. If any fields here have custom values, those will take priority over your en.json entries—either update them here or clear the custom values to let the theme’s translations take over.

• Ensure Optimized Checkout is enabled
  The optimized_checkout block only applies to BigCommerce’s modern Optimized One-Page Checkout. If your store is still using Classic Checkout, this block won’t work. Verify this in Store Setup > Checkout—make sure "Optimized One-Page Checkout" is toggled on. For Classic Checkout, you’ll need to look for different translation keys (often prefixed with checkout_ instead of optimized_checkout).

• Look for theme-specific checkout overrides
  Some Stencil themes (including Laparis) might have custom checkout templates that hardcode text or use separate language files. Check the theme’s templates/checkout/ directory for any .html files that might have hardcoded strings, or see if there’s a dedicated checkout.json language file in the lang/ folder.
