If your RSS widget doesn’t update, or doesn’t update frequently enough, add the next wordpress code to your current theme’s function.php:
add_filter( ‘wp_feed_cache_transient_lifetime’, create_function(‘$fixrss’, ‘return 1800;’) );
Now the feeds links will be checked every 1800 seconds / a half-hour !
I tried the code for today news and going extremely well!
