I am talking about the mode where you have page numbers at the bottom. You click on a page number and it loads it. In that scenario, clicking on a page number does a full reload of the entire wordpress site. So if your plugin is inserted at the bottom of the site, everything scrolls to the top. Is it possible to active Ajax for that ?
However I see that in the second mode (where you have a “load more” button that dynamically adds new posts below the others) it works perfectly, without a full reload of the wordpress site.
