 * Hi,
 * Recently my website [http://www.manojblogszone.com](http://www.manojblogszone.com/)
   got updated with wordpress version 4.5.3 and everything is fine and one can see
   the website but when I logged into my admin section I am seeing one error line
   on top and its saying
    “Warning: call_user_func_array() expects parameter 1 to
   be a valid callback, function ‘wp_admin_canonical_url’ not found or invalid function
   name in /home/manojblo/public_html/wp-includes/plugin.php on line 525 “
 * Please help me resolve it.
 * Thanks,
    Manoj Kumar Sethi
