I'm using 2.3, and I've been having a strange error lately.
PHP Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/blog/wp-includes/wp-db.php:160) in /var/www/html/blog/wp-includes/feed-rss2.php on line 2
I've been yet to be able to reproduce what is causing the error. I'm not sure what to look at, I've looked at all my feeds on my home page, individual posts, comments, individual post comments, pages. Everything looks fine.
I've just checked a couple of the ip address that I saw repeatly getting this error, it looks like google and yahoo. Anyone else seen/experiencing this?
