Hello,
Thank you for reaching out to us.
– ?wc-ajax=get_refreshed_fragments is the default WooCommerce request to update cart in header and also wishlist. Unfortunately, the theme does not have options to speed it up. You can read this topic and maybe find any solution suitable for you https://wordpress.org/support/topic/wc-ajaxget_refreshed_fragments-5/
Or you can disable Ajax Cart Fragments – Theme Options > Speed Optimization > Always Load Wc-Cart-Fragments > off. Ajax Cart Fragments option allows you to sync the number of products in the header mini-cart if you open your site in a few browser tabs.
– In order to resolve the issue with /wp-admin/admin-ajax.php, we suggest that you edit home page with Elementor > edit the relevant XStore widgets using Elementor > Edit the relevant element > Advanced > XStore Ajaxify > Lazy Load > Toggle it OFF and Publish it.
– Review your active plugins and disable or remove any unnecessary plugins that may be contributing to excessive AJAX usage.
– Implement a reliable caching solution such as WP Rocket, W3 Total Cache, or LiteSpeed Cache (if supported by your server). These plugins can help reduce the number of AJAX calls and improve overall site performance.
– A Content Delivery Network (CDN) can offload static resources and reduce the load on your server, improving response times for users globally.
Warm Regards,
The 8Theme Team
