I’ve set correct settings for WooCommerce Infinite Scroll and Ajax Pagination plugin – https://xstore.helpscoutdocs.com/article/65-woocommerce-infinite-scroll-and-ajax-pagination-settings If you do not want the Infinite Scroll, you can disable this plugin.
I’ve sent the mentioned PHP warning to our developers, it should not cause any problem on your site, so you can ignore it right now. We will check it more deeply from Monday, to fix it in the next update. We will contact you if any additional information needed. Thanks for the report.
