Weird Wordpress Error - Server Issues/ htaccess/ functions.php

Anyone know why this URL works flawlessly: http://plumcreekgarlic.com/

But this URL leads to a Wordpress error? http://www.plumcreekgarlic.com/

Is this is a Wordpress issue or a server/ a-record/ htaccess issue?

Thanks!

I found this thread http://wordpress.org/support/topic/cannot-modify-header-information-pluggablephp-on-line-865?replies=9

It says to check the functions.php if there are spaces before the starting <?php tag and after the ?> closing tag.

Quoting Shane G:

1. Download the file mentioned in the error message.
2. Open that file in a plain text editor
3. Check that the very first characters are
4. Check that the very last characters are ?>
5. Place the cursor between the ? and >
6. Now press the DELETE key on your computer and keep that key pressed for at least 15 seconds.
7. Now type > and
8. Save without pressing any other key at all.

If this fixes it then it's a WordPress problem. You might have a plugin that redirects users using www.plumcreekgarlic.com to plumcreekgarlic.com, but then as error says, header information (location) cannot be sent when output is started already.

If you have such a plugin, the delete this and use htaccess to redirect users:

RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
