include_categories not working

Here’s my shortcode:

[image_wall image_sizes=’thumbnail, medium’ column_width=” batch_size=’20’ buffer_pixels=’200′ support_author=’false’ move_to_end=’false’ column_proportion_restrictions=’2.0′ open_links_in_new_window=’true’ include_categories=’food-porn’ exclude_categories=” include_tags=” exclude_tags=” include_pages=’true’ background_color=’white’ gutter_pixels=’8′ corner_radius=’0′]

https://spoonuniversity.com/food-porn

I have multiple posts in the Food Porn category (slug: ‘food-porn’), but when I view the page, the ‘loading more images’ pop up appears, disappears, and reappears for a while then finally one image linking to a random page appears. Any idea how to fix?

Thank you!
