hello. i had a similar problem and didn’t notice this post.
i solved it by manually adding following to the theme file:
<script type="text/javascript" src="/wp-content/plugins/catch-infinite-scroll/public/js/catch-infinite-scroll-public.js?ver=2.0.3" id="catch-infinite-scroll-js"></script>
and modifying the file a bit by including the settings. you’d just need to insert following to the js file
var selector = {
contentSelector: "REPLACE-WITH-YOUR-CONTENT-SELECTOR",
event: "scroll", // OR click
finish_text: "No more items to display",
image: "/wp-content/plugins/catch-infinite-scroll/image/loader.gif", // OR relative url to your custom image
itemSelector: "REPLACE-WITH-YOUR-ITEM-SELECTOR",
jetpack_enabled: "false", // OR true IF YOU GOT JETPACK
load_more_text: "Load More",
navigationSelector: "REPLACE-WITH-NAVIGATION-CONTAINER",
nextSelector: "REPLACE-WITH-LINK-TO-NEXT-POST",
theme: "REPLACE-WITH-YOUR-THEME-NAME",
type: "post" // this is hardcoded
};
