Sir, How to showing post author for CPT

Not sure on the post count portion, that’d be something that should be getting handled by WordPress core, and it’s not a setting/detail we’ve intentionally prevented from working.

Regarding authors, sadly there’s going to need to be some code for this. The snippet below will fetch all the post types registered with CPTUI and include them in the author archive query

function my_cptui_add_post_types_to_archives( $query ) {
	// We do not want unintended consequences.
	if ( is_admin() || ! $query->is_main_query() ) {
		return;    
	}

	if ( is_author() && empty( $query->query_vars['suppress_filters'] ) ) {

		// Replace these slugs with the post types you want to include.
		$cptui_post_types = cptui_get_post_type_slugs();

		$query->set(
	  		'post_type',
			array_merge(
				array( 'post' ),
				$cptui_post_types
			)
		);
	}
}
add_filter( 'pre_get_posts', 'my_cptui_add_post_types_to_archives' );

sorry, where i add this code sir? thanks

The best place is likely going to be your active theme/child theme’s functions.php file. However, we can also provide a quick plugin with just this code in it as well, if you prefer something you can install and activate instead.

so, tell me the plugin, sir
thanks

sir that code is fully inserted to theme function.php?
full of that code? or any something have to modify?

I have created a quick plugin for you to activate and install that has all and only the code I provided above. You can find a zip copy of it at https://www.dropbox.com/scl/fi/zsdoruipkcpslupbk2mw9/havidz-cptui-posts-in-author-archives.zip?rlkey=ydy76wqqnwvmoqvxrapvt601l&dl=0

This should save you from having to copy/paste/save to a functions.php file.
