Welcome to the CodeIgniter forums!

You probably have a trailing whitespace after the closing PHP tag. Remove the closing PHP tag completely, and the error should go away.

It's a good idea to omit the closing PHP tag from all of your files to avoid this from happening, as per the [url="http://ellislab.com/codeigniter/user-guide/general/styleguide.html#php_closing_tag"]CodeIgniter Style Guide[/url].
