Warning: Cannot modify header information - headers already sent by (output started at /******* edited ****/wp-content/themes/atahualpa/header.php:2) in /******* edited ****/wp-includes/pluggable.php on line 692
I'm using 3.4.6 and this message is coming up when a user edits their profile by changing their password. Using pico from the command line I've verified there are no extra lines in wp-config, header.php, or any other file I've ever edited. My next thought was that perhaps my .htaccess file in /wp-admin denying all except my IP was the problem so I added 127.0.0.1 and that didn't do it either.
Here's line 2 in header.php (no spaces after it):
<html xmlns="http://www.w3.org/1999/xhtml" <?php language_attributes(); ?>>
Any ideas Flynn?
