I've just come across a problem with 2.7. After deleting the previous version and upgrading to the new one, I go to /wp-admin/ and get this message:
Warning: Cannot modify header information - headers already sent by (output started at /home/migueldorneles/www/blog/wp-config.php:1) in /home/migueldorneles/www/blog/wp-includes/pluggable.php on line 850
What could it be? How can I resolve that?
Thanks in advance.
