			'piklist' => 'D:\wamp\www\karestan\modules\cms-vavak/modules/piklist/lang/piklist-fa_IR.mo'
		);
	}
	function load_php_file_key(){
		
		return array(
			'duplicate-post',
			'piklist'
		);
	}
	
}

two function load_php_file and load_php_file_key have a complex syntax but for better comprehension i write this array for return .

screenshot

otherwise i include custom .mo file for piklist.
add_filter ('load_textdomain_mofile', array($this, 'override_load_textdomain_theme'), 10, 2 );

with this function change piklist default language and custom .mo file and replace in language piklist directory. when disable this function system is safe and no problem

when write new post in admin after save post, post status change to Draft and this notice show in my log.debug
