The code of rel=”EditURI” and rel=”wlwmanifest” is only for Windows Live Writer to offer the posts for your wordpress blog, if you do not need them, you can del them as follows:
Method 1:
1.Login to your WordPress admin panel
2.Navigate to Appearance > Editor
3.Click Theme Functions (functions.php) from the Theme Files section
4.Add the following code to the end of the file. Just before the closing <?php } ?> or ?> tags:
add_action(‘init’, ‘remheadlink’);
function remheadlink() {
remove_action(‘wp_head’, ‘rsd_link’);
remove_action(‘wp_head’, ‘wlwmanifest_link’);
}
5.Click the Update File Button and go view the source code of a page on your site
Method 2:
If the other plug-ins do not need <?php wp_head(); ?>, you can delete <?php wp_head(); ?> directly, then not need to add the above code.
Method 3:
Go to wp-includes, open default-filters.php, at about line 180, you can find the following codes:
//add_action( ‘wp_head’, ‘feed_links’, 2 );
//add_action( ‘wp_head’, ‘feed_links_extra’, 3 );
//add_action( ‘wp_head’, ‘rsd_link’ );
//add_action( ‘wp_head’, ‘wlwmanifest_link’ );
