 I've got this error whenever i try to edit any post:
 {{{
 Warning: Cannot modify header information - headers already sent by
 (output started at /home/anduriel/public_html/wp-includes/post-
 template.php:166) in /home/anduriel/public_html/wp-includes/pluggable.php
 on line 856
 }}}

 I can't edit post. If  i change line 856 for this one:

 {{{
 echo "<meta http-equiv='refresh' content='0;url=$location' />";
 }}}

 Apparently works in post editing.
 But this error happens also when an Editor profile try to access to admin
 panel or even making a new post

 {{{

 This happens to me in the even with the last branch.
