WordPress MU

I'm using WPMU with another code-igniter application. WPMU installed in a sub-domain. In the template's side bar display the posts of a particular category. Now I want to display these posts in to the pages of code-igniter application.

I tried to include the wp-blog-header & run wp functions but it gives me

Warning: Cannot modify header information - headers already sent by (output started at /hermes/.../index.php:7) in /.../wpmu-settings.php on line 135

Any Idea how I can get the posts in external files.

Thanks in advance

Well first of all you've got a trailing blank line in one of your php files.

thnx for reply.. I solved the problem..

In case of of normal wordpress installation this method working but not working with subdomain installation of WPMU.

To solve the issue i just create a new page template which show only the posts of that particular category. Then I use the page URL to display the posts.

I think it's not a good solution bt it's working good.

If u have any batter solution pls..

Thanks
