 * I’ve got an installation of WP 2.5.1 going, but for some reason it’s giving me
   some trouble. At the login page, these errors are showing up:
 *     ```
       Warning: Cannot modify header information - headers already sent by (output started at /home/robotguy/public_html/wordpress/wp-content/themes/sr/functions.php:6) in /home/robotguy/public_html/wordpress/wp-login.php on line 202

       ```
   
 * What’s the solution? I Googled the error, and others have had the same problem.
   However, I was not able to find a solution.

 * I just deleted my functions.php. It was empty, since I had removed my functions
   from it, so I guess some empty spaces were causing the problem.
