Common Issues

Last updated September 2, 2026

Customize button does not appear on product page

  • Confirm Enable customization is ticked in the product’s Product Customizer meta box.
  • Check the product configuration was saved (open Configure Customizer and save even without changes).
  • Clear any page cache.
  • Check your theme for filters on woocommerce_before_add_to_cart_button that might suppress the button.

Editor opens but canvas is blank / gray

  • Open browser console for JS errors.
  • Check that your view’s background image URL is reachable (copy the URL and open in browser).
  • Verify the canvas width and height are greater than zero.
  • Try a different browser to rule out extension conflicts (ad blockers sometimes break CDN-loaded Fabric.js).

Fonts show as default sans-serif in editor

  • Go to Sigmira → Fonts and confirm the font is active.
  • Check the font family name matches between regular/bold/italic variants.
  • Reupload the font as .woff2; some .otf files fail to load in browsers.
  • Check browser network tab: the font file should return 200, not 404 or 403.

Clipart does not appear in editor

  • Check Sigmira → Elements: asset is active, category is active.
  • Verify the print method does not restrict the category the asset belongs to.
  • Verify the product’s element overrides do not disable clipart.
  • Try a different user account (browsing as customer vs admin).

Pricing does not update live

  • Confirm at least one pricing rule is active at Sigmira → Pricing Rules.
  • Verify the rule scope matches the product (global, or scoped to this product).
  • Check browser console for errors when the price should update.
  • Make sure the customer’s actions actually trigger the rule (e.g. adding a text element for a text-length rule).

Design does not appear on the order

  • Confirm the order item was created via Sigmira checkout (not manually added).
  • Check Sigmira → Dashboard → Designs to see if the session exists.
  • Look for errors in debug log at the time of checkout.
  • Verify the WooCommerce cart integration hook is firing (no other plugin is intercepting the add-to-cart flow).

Export job is stuck on “Processing”

  • Wait: complex designs at 300+ DPI can take 1-2 minutes.
  • If it has been >5 minutes, reload the order page.
  • If still stuck, check Sigmira → License for quota issues.
  • Run wp sigmira exports retry-failed to retry stuck jobs.
  • Check server error logs for PHP memory or timeout errors.

License activation fails

  • Confirm you copied the full license key (no extra whitespace).
  • Check your server can reach the license server (no firewall blocking outbound HTTPS).
  • If you recently moved domains, the license may be tied to the old domain. Contact support for a transfer.
  • Try again after a few minutes in case the license server is temporarily down. If so, Sigmira enters grace period automatically.

Customer sees “Design expired” error

  • Design sessions expire after 30 days by default. If a customer takes longer than that to check out, the session is gone.
  • For saved designs, expiration does not apply; the design is permanent until deleted.
  • Adjust expiration in Sigmira → Settings if your catalog has long buying cycles.
