Problem: You are using the latest versions of WPML Multilingual CMS and WPML String Translation on a WordPress site with the Porto theme and WooCommerce. When manually adding products on the edit order page and clicking Recalculate, the products disappear. This issue does not occur with older versions of these plugins. Solution: We recommend checking the following errata page for a known issue that matches your description: https://wpml.org/errata/b2b-for-woocommerce-product-removed-when-adding-items-to-existing-order/. A permanent fix is expected in the next release of WCML. If you are considering rolling back to previous versions of the plugins on your live site, it is generally safe, but ensure you test thoroughly on a staging environment first.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If issues persist, please open a new support ticket.
