This means some text was sent to the browser inadvertently.  Double  
check the top & bottom of your config file(s) that there's no space  
before or after the <?php at the top or the ?> at the bottom.  The  
closing PHP tag is optional -- it's safe to simply remove it from the  
bottom of the file.

If there's any output whatsoever -- a space, a return character,  it  
will throw an error.
