RESOLVED!
Solution:
1º Download a HEX EDITOR SOFTWARE
2º Open “functions.php” with Hex Editor
3º Delete “invisible characters” before <?php
NOTE: Opening functions.php with Notepad or Dreamweaver doesn’t show any of this “invisible characters”.
The initial problem is solved, but now, every time i try to change a page (and it calls “wp-admin/post.php”) i get the same error:
Warning: Cannot modify header information – headers already sent by (output started at /home/site/public_html/v2/wp-content/themes/feast/functions.php:1) in /home/site/public_html/v2/wp-includes/pluggable.php on line 880
The first thing that i’ve done was “re-checking” again the white spaces (<?php ?>) but everything is OK.
Suggestions?
