Having trouble setting blog up?

I cant set blog up with www.mydomain.com/keyword/ it goes to mydomain.com/keyword/ without the www. this then gets a page no found error.

How do I get round this, Im using Word press.

 

Put http://www.mydomain.com/keyword/ in General Settings > Blog Address (URL), then click Update Options.
http://codex.wordpress.org/Settings_General_SubPanel

 

do u have 301 redirect for non www to www ?

update the blog url to

http://www.site.com/keyword/

Code (markup):

also the files location.

which host are u on?

 

I like to use the "enforce-www-preference.php" plugin to keep the www. in all links.

 

Wow guys, thanks for this.
