The WordPress 404 page customization using the ProductX WooCommerce Builder is super easy. The process is similar to building other pages using the builder.
Please note that you will need to turn on the ProductX WooCommerce Builder Addon for this to work:

The process is simple:
- Go to ProductX > WooCommerce Builder from your WordPress dashboard.
- You will find the 404 page in the WooCommerce builder.
- Just click on the WooCommerce 404 page section. You will see the option to start from scratch. However, if you have page templates ready, you will see them on the builder dashboard.
- Just click on the “Start from scratch” option. You will be taken to the WordPress 404 page template.

- Now you can design the 404 page using the assets you need. You can use ProductX blocks to do this. You can also use some pre-made templates.
- You do not have to set any conditions for this page as it is a standalone page.
- Finally, publish the page.
Here’s how it will look on the front-page:
