your custom post should derive from WP_Post, many plugins including this one hook save_post and this hook is expecting to receive a WP_Post as defined in WordPress. If the post is not of the relevant type it will exit without taking any action.

How are you triggering save_post and Is there a problem with the post you are trying to save?

do_action('save_post', 0, NULL, false)

the standard wp_insert_post() saves the post and gets the ID from the insert before proceeding to call:

	/**
	 * Fires once a post has been saved.
	 *
	 * @since 1.5.0
	 *
	 * @param int     $post_ID Post ID.
	 * @param WP_Post $post    Post object.
	 * @param bool    $update  Whether this is an existing post being updated or not.
	 */
	do_action( 'save_post', $post_ID, $post, $update );

If there is an error on save the code bails and doesn't get this far, so in normal use this would never get called with zero and null... are you triggering this action in a different way?

At least I have plenty of custom post types and not seen this type of problem.

@BioSs54 is this still a problem?

[BioSs54]

I solved problem by a reset of all plugins. My bad, sorry. :(
