404 Error for WooCommerce Block Editor CSS Asset

closed Sep 25, 2025 Plugin → Woocommerce

Summary:

A 404 (Not Found) error occurs when the WordPress block editor attempts to load the CSS file plugins/woocommerce/assets/client/blocks/email-content.css. This missing resource is likely a stylesheet intended for WooCommerce-related blocks within the post editor.

The issue is caused by a reference to an asset file that does not exist in the WooCommerce plugin's build. This could be due to a misconfiguration in the plugin's block registration, an incorrect file path, or the file being omitted from the production build. The impact is a failed network request visible in the browser's developer console. While the visual styling of the editor or the blocks might not be severely affected if there are fallback styles, the error indicates an underlying problem with the plugin's asset management.

How to Replicate:

  1. Install and activate the WooCommerce plugin.
  2. Navigate to the Posts section in the WordPress admin dashboard.
  3. Open an existing post or create a new one to enter the block editor.
  4. Open the browser's developer console (F12) and check the Network tab for a 404 error related to email-content.css.
