Hi,
Can you enable debug in your wordpress and check if you see any error for this plugin, best is disable all plugins and then our plugin and then enable other plugins that adds custom post types to test easily.
How to enable debug in wordpress https://codex.ww.wp.xz.cn/Debugging_in_WordPress
define( ‘WP_DEBUG’, true ); in your wp-config.php
Note: enable debug is for testing purpose, we suggest not keep debug enabled in production.
Activated wp_debug but no luck, not showing any error.
Hi /feed may not work if your site has permalink disabled. without debugging it’s not possible to check. Another thing is , please check the plugin configuration that you checked the custom post types
