Edit: Summarized the message
I get this error:
“Warning: Cannot modify header information – headers already sent by (output started at /home/myusername/domains/mysecretdomain.com/public_html/index.php:2) in /home/myusername/domains/mysecretdomain.com/public_html/blog/wp-includes/pluggable.php on line 865”
When I add
‘<?php
define(‘WP_USE_THEMES’, false);
require(‘/blog/wp-blog-header.php’);
?>
‘
to the place where I want the blog to go. However when I access my blog at my.url/blog/index.php it runs fine.
