Not PHP 8 compatible

PHP 8.0 and above

Fatal error: Uncaught Error: Call to undefined function create_function() in /wp-content/plugins/royal-recent-posts-widget-by-category/royal-recent-posts-widget-by-category.php:253 Stack trace: #0 /wp-admin/includes/plugin.php(2314): include_once() #1 /wp-admin/plugins.php(192): plugin_sandbox_scrape(‘royal-recent-po…’) #2 {main} thrown in /wp-content/plugins/royal-recent-posts-widget-by-category/royal-recent-posts-widget-by-category.php on line 253

If you fix this by changed the widget_init:

function register_royal_recent_posts_widget_by_category() {
	return register_widget("RRPWbC");
}
add_action( 'widgets_init', 'register_royal_recent_posts_widget_by_category');

Then the next error is:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function WP_Widget::__construct(), 0 passed

Additional sidenote: all the $instance variables are not checked if the exists, when you didn’t setup the widget before a lot of notices/warnings will popup with debug mode on.
