I am getting the error:
Warning: Cannot modify header information - headers already sent by (output started at /home/greenbi5/public_html/wordpress/wp-content/themes/gbp/functions.php:20) in /home/greenbi5/public_html/wordpress/wp-includes/pluggable.php on line 868
only when putting "www" in the URL.
this: http://greenbirdproductions.com/wordpress/home works just fine.
this: http://www.greenbirdproductions.com/wordpress/home has the error.
It's my first manual install of WordPress, so I'm assuming it has something to do with that. My knowledge of php is minimal.
I do not have any extra spaces before <?php or after ?> in the wp-config file - or in the two files it mentions in the error. There doesn't seem to be any extra spaces in line 20 of functions.php.
(And, though this doesn't matter, it hasn't been styled for IE yet, so it probably looks a little goofy if you view it in IE.)
Any help would be greatly appreciated. Thank you!!
