I added YITH WooCommerce Ajax Product Filter to the catalogue pages side bar for the product tags. And it is not working correctly. After checking the box the filtered products are shown without photos. You can check for example from this page: https://teamylove.ru/product-category/vitamins/
Is it filter and theme compatibility issue? If so, which filter could you recommend to use?
Regarding above request, I found out that the AJAX filter is not working properly because of W3 Total Cache plugin and its lazy load mode for thumbnails. Which Cache plugin would you recommend for your theme?
All cache plugins are compatible with our themes. You might have faced problems due to coordination with other plugins. But you can try out with some other cache plugins such as https://wordpress.org/plugins/litespeed-cache/
