Thank you for your fast response 😉
Working but reading better here i realized that ‘0’ is not a best ‘unique id’ for your plugin 😀
better correction:
wp_register_sidebar_widget('network_latest_post',__("Network Latest Posts",'trans-nlp'),"network_latest_posts_widget");
wp_register_widget_control('network_latest_post',__("Network Latest Posts",'trans-nlp'),"network_latest_posts_control");
Thanks again 😀
