Hey i am getting an error on my site,

If you can read this, this is a script problem and not a server problem
Warning: Cannot modify header information - headers already sent by (output started at /home/anime/public_html/index.php:4) in /home/anime/public_html/wp-includes/pluggable.php on line 390

Does anyone know what this means?

Thanks
Kev

It means that you are trying to modify your headers after they have already been sent. This usually means that you are using the header() function after you have already provided output.

Hey thanks!

Everything now sorted!
