databell96 on "[Plugin: Ajax Load More - Infinite Scroll] No posts are loading after initial posts"

I've been using ALM for about a year. Always worked great, but now for the first time, I m using one without the Load More button. So just infinite scrolling as you go down past each series of ten posts. Got this for my shortcode:

echo do_shortcode( '[ajax_load_more post_type="food, film, music, art, fashion, photography" posts_per_page="10" max_pages="0"]' );

First ten posts load great, but once I scroll downward, I get the loading dots, but no more posts. So I'm wondering if I'm doing something incorrect.

Problem is this is on a staging site that is password protected, so I can't share a link with you.
