Plugin Not Working in WooCommerce Cart Block or Widget

Problem Description #

The free-shipping bar is missing from (or not updating inside) the new WooCommerce Cart/Checkout Blocks, block-based cart widgets, or page-builder mini-carts.

Common symptoms

• Nothing visible in the header mini-cart or cart widget.
  
• The plugin appears on the standard /cart/ page but not in block-based cart or checkout templates.
  
• The plugin doesn’t update when cart widget content changes across the site.
  

Cause

• The WooCommerce Cart & Checkout Blocks (and some page-builder cart widgets) do not use the same PHP rendering hooks or update paths as classic templates; some blocks rely on REST/JS rendering. The plugin historically supported classic shortcode/cart but may need specific integration or updated compatibility for block-based carts. Support threads show this is a frequent compatibility area.

Solution (step-by-step)

1. Confirm where you want the bar displayed: If you only need it on classic Cart/Checkout pages, add the plugin there (shortcode or built-in positions). If you need the bar in a header mini-cart or block widget, continue the steps.
   
2. Check plugin settings positioning: Admin → Display Settings → choose a position that targets the block if possible (some positions are only for classic cart templates).
   
3. Check WooCommerce Blocks version: Ensure WooCommerce Blocks and WooCommerce are updated, older Blocks versions can cause false incompatibility reports. The plugin author reported some older Blocks bugs are fixed in newer Blocks releases. WordPress.org
4. If using a block-based site or theme with header cart widget: Try placing the plugin shortcode inside the same block where the mini-cart renders (if page builder permits) instead of a global header area.
   
5. Disable aggressive caching on cart widget: If your cart widget is cached, disable caching for the cart or exclude the widget from CDN caching. Test again.
   
6. If using a page-builder (Elementor/Divi/Oxygen):
   
   • Make sure you’re placing the plugin output into a dynamic area which is updated by AJAX (if your page builder provides dynamic fragments).
     
   • For Elementor: test by adding the plugin shortcode into an Elementor HTML/Text widget placed inside the Cart template.
     
7. If you still don’t see the bar: Contact plugin support with a URL and screenshots; include theme name, page-builder name/version, and WooCommerce Blocks version. Plugin devs have investigated and provided targeted fixes in several threads. WordPress.org

Prerequisites

• Latest WooCommerce Blocks (if using block-based cart) and plugin version.
  
• If possible, a staging copy for testing.

Additional Notes

• Block-based themes and the modern WooCommerce Blocks system sometimes require plugin updates to support REST-rendered cart fragments, plugin authors often patch or advise on compatible positions. WordPress.org
