 * Hi WP,
 * When I type in URL.com my site works fine, but when I type in [http://www.URL.com](http://www.URL.com),
   I get this error?
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/content/09/8035009/html/index.php:1) in /home/content/09/8035009/html/
   wp-includes/pluggable.php on line 866
 * Any thoughts on how to fix it?
 * Thanks!
