Deprecated function “create_function” in PHP 7

Seeing errors when upgrading to PHP 7.2+. Deprecated: Function create_function() is deprecated in /wp-content/plugins/wp-posts-carousel/carousel-widget.class.php on line 382 Looks like you need to adjust the function to be as follows on line 382 of carousel-widget.class.php: function yourmodifier_register_widgets() { register_widget( 'WpPostsCarouselWidget' ); } add_action( 'widgets_init', 'yourmodifier_register_widgets' ); The function you used is anonymous and it really should have a name, as described above, so the plugin can be extended and so it complies with PHP 7+. Let us know if you do that, because we’d love to use your plugin instead of our edited version.
