extend ideas page not working

I just went to post a new idea in the extend section and after clicking on submit I am getting the following error:

Warning: Cannot modify header information – headers already sent by (output started at /home/wporg/public_html/extend/ideas/config.php:64) in /home/wporg/public_html/extend/ideas/bb-includes/pluggable.php on line 160

Just thought I would inform you that your system is a little bit broken at the moment.
