 * When someone attempts to access my website without typing www before the URL,
   they receive the following error:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/hdi2/public_html/index.php:1) in /home/hdi2/public_html/wp-includes/
   pluggable.php on line 390
 * I have no idea what to do here. I thought that maybe this might have been some
   kind of permissions issue but, I have went through everything and set the proper
   permissions. Does anyone know how to fix this kind of problem?

 * Look at your /home/hdi2/public_html/index.php file. See if the first line is 
   a blank one or some such thing.

 * Nope. Here are all of the lines from the index.php file:
 * <title>Official Weblog Of Howie Isaacks</title><?php
    /* Short and sweet */ define(‘
   WP_USE_THEMES’, true); require(‘./wp-blog-header.php’); ?>
 * Thanks for the suggestion though. I’m sure it has something to do with a bad 
   or missing line of code.

 * Remove this:
    `<title>Official Weblog Of Howie Isaacks</title>` You should NEVER
   edit that file. You edit only the index.php of your active theme.

 * OK. So put back a fresh copy of the index.php that I should “never” edit. Nothing
   has changed. I still have the same problem.

 * Clear your browser cache or something, perhaps?

 * The problem isn’t with my browser or the other people’s browsers. I have cleared
   the cache a couple of times. I’m pretty sure there’s some screwed up code someplace.

 * I am getting the same error today after transfering my blog from one host to 
   another.
 * the only thing I have changed is updated my wp_config file.

 * Thanks RocketSeason. None of the fixes on your thread worked 🙁

 * It looks like the problem was caused by a title having been added to my main 
   index.php file. I removed the title line altogether and the problem is solved.
