Warning: Cannot modify header information - on my blog

Does anyone know what this error is about,

Warning: Cannot modify header information - headers already sent by (output started at /home/content/b/b/r/bbrian017/html/casinofiery/wp-content/themes/ClassicPoker/functions.php:8) in /home/content/b/b/r/bbrian017/html/casinofiery/wp-includes/pluggable.php on line 694

Code (markup):

I get the error when I visit the website using www. but when I don't use the www. the error doesn't show up.


Any advice?

 

My guess is that the script is trying to redirect or set a header when some output has been already been sent to the browser.

What's in ClassicPoker/functions.php on line 8?

 

You already made output before header command. Remove ouput.

 

I personally didn't add anything to the functions.php I'm assuming it's an error from when this free template was designed?

Anyone have a clue how to fix this?

this is the functions.php file here,

I'm at work and had to use notepad to show this code. So I'm not too sure where line 8 is but I'm pretty sure I have added it here!

 

Oh yes jestep is right on this: pluggable.php tries to redirect to the www-less URL. In order for this to get completely solved, you need to add rewrite rule in your htaccess that redirects www to www-less URL.

RewriteCond %{HTTP_HOST} ^[url]www.casinofiery.com[/url] [NC] 
RewriteRule ^(.*)$ http://casinofiery.com/$1 [R=301]

Code (markup):

 

oh jeepers what file do I add that too?

RewriteCond %{HTTP_HOST} ^www.casinofiery.com [NC]
RewriteRule ^(.*)$ http://casinofiery.com/$1 [R=301]

Code (markup):

P.S. I also get the error when I save or edit anything in the admin cp. the changes save but I still get this error!

 

.htaccess file.

 

I know I have issues with .htaccess access files using godaddy.

I don't currently have one in my root folder do I simply create one

 

Yes but you will need to add this as the first line:

RewriteEngine ON

 

Can I create this .htaccess file using notepad?

and if so what do I save it as all files and a .php? I'm a little confused sorry...

RewriteEngine ON
RewriteCond %{HTTP_HOST} ^[url]www.casinofiery.com[/url] [NC]
RewriteRule ^(.*)$ http://casinofiery.com/$1 [R=301]

Code (markup):

Like that?

 

Yes. Most important: upload it in ascii mode.

 

I uploaded the file but I'm sure I didn't do it correctly.

Any ideals?
