[Remove WP Version Number] Hackers usually look for version number first when checking for vulnerabilities. By default wordpress prints the version number in header, rss feed, scripts and styles. #wordpress #security

functions.php

# In template file functions.php

# Remove version from header:
remove_action('wp_head', 'wp_generator');

# Remove version from RSS feed
function remove_version_info() {
  return '';
}
add_filter('the_generator', 'remove_version_info');

# Remove version number from scripts and styles files
function remove_version_from_style_js( $src ) {
  if ( strpos( $src, 'ver=' . get_bloginfo( 'version' ) ) )
    $src = remove_query_arg( 'ver', $src );
  return $src;
}
add_filter( 'style_loader_src', 'remove_version_from_style_js',9999);
add_filter( 'script_loader_src', 'remove_version_from_style_js',9999);
