 * Hi, I keep getting error messages along similar lines to the following:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home5/backlane/public_html/wp-content/themes/starkers/functions.php:3) in/
   home5/backlane/public_html/wp-includes/pluggable.php on line 865
 * It happens during plugin installations through dashboard, and also when I take
   the www. off my urls.
 * I first noticed the problem occuring after following the instructions on this
   website ([http://www.blogohblog.com/adding-extra-sidebar-to-your-wordpress-theme/](http://www.blogohblog.com/adding-extra-sidebar-to-your-wordpress-theme/))
   to create a new sidebar, and I think when I edited the functions php file, something
   was upset. I have been trying to find other threads on similar problems, but 
   it’s difficult to describe to a search engine the problem. Anyone have any ideas?

 * It’s fine, I’ve resolved this myself- no spaces outside the php enclosings on
   a php file. I love wordpress!!!!!!!!!
