Correction for relative links:
<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" />
should be
<link rel="shortcut icon" href="./favicon.ico" type="image/x-icon" />
if ‘favicon.ico’ in the same directory as ‘index.php’. You’ll have to add the file and the head text to the root folder for WP as well as to the ‘wp-admin’ folder.
