A widget does not appear
Check that the widget is enabled under Inference Works → Recommendations → Widgets and that WooCommerce is active. “Frequently bought together” appears only for simple products that have matches. If suggestions are missing, rebuild the data in the Data tab.
Few or poor suggestions
A new store has few orders, so the plugin relies on category and attribute similarity and bestsellers. Check your product categories and attributes, the weights in the Similarity tab and the order statuses in the Data tab. An administrator with WP-CLI access can rebuild the data or save a dry-run report:
wp iwrec rebuild– rebuild the data,wp iwrec rebuild --dry-run --report=iwrec-report.json– a dry-run report that changes no data.
The dry-run report is saved in the plugin’s folder inside the uploads directory and changes nothing in your store.
Old styling or outdated products
Clear your page, optimizer and CDN caches. Cart and recently viewed widgets load in the browser, so check the browser console for blocked JS files or REST requests.
Customizing the widget
Copy templates/widget.php to your-theme/inference-works-recommendations-for-woocommerce/widget.php and edit the copy in your theme.
Pro or the license is not working
Check that the Pro edition is active, that the key belongs to this product and that your plan has a free activation. See license and Pro activation. When contacting support, include your WordPress, PHP, WooCommerce and plugin versions, your theme and the steps to reproduce the problem. Remove license keys and customer data from any attachments.
