Hide the WordPress Version Number
Strips the WordPress version string out of your site's <head>, so it's not sitting in plain sight for anyone scanning your site for a known vulnerability tied to a specific version.
php
/**
* Remove WordPress version.
* Better to hide it and keep hackers in the dark.
*/
function remove_wp_version() {
return '';
}
add_filter( 'the_generator', 'remove_wp_version' );
