Hi,
I’ve searched as long as possible in the forum.
I’ve read the documentation.

The ajax form search fields and reset, works well.
But I can’t get infinite scrolls to work.

I’ve tryed with shortcode. I’ve put the shortcode in the WP classic editor. I’ve copied results.php in a subfolder of my theme (that is elementor hello theme) and I pasted in, the code of the results-infinite-scroll.php template.
In the settings the result url is filled etc etc.
Nothing. Scrolling nothing happens.

Then I’ve tryed with custom setting. I’ve set a custom template in my theme with the code of the results-infinite-scroll.php template customized.
In the settings the result url is filled etc etc.
Ajax container = #main
Pagination Type is set to infinite scroll; show loading icon checkbox is checked, but it’s not loaded.
Post result selector = .search-results-item (but I’ve tryed without it, too)
Infinite Scroll Container: = empty (but I’ve tryed with #search-filter-results-list, too)
I’ve tryed all the other fields of the Ajax Pagination setting section, but nothing.
I’ve deactivated all plugin except ACF Pro, Custom post type UI and S&F Pro of course. Nothing
I’ve changed the theme with a default one. Nothing.

The page is on a live web site that I’m developing. I can give the url but not publicly

Thanks in advance for your help
