wooninjas on "Cant access admin section of my wordpress site"

I recently uploaded my wordpress eCommerce site http://www.kokokraa.com from my local sever. The homepage is displayed but I'm not able to enter the admin section of the website. when I type http://www.kokokraa.com/wp-admin, I get the following error message: Waing: Cannot modify header information - headers already sent by (output started at /home/kokokraa/public_html/wp-content/plugins/woocommerce/includes/admin/wc-admin-functions.php:2) in /home/kokokraa/public_html/wp-includes/pluggable.php on line 1196.
Subsequently I cant do anything about my roken links since I cant get into the admin section. Please help me somebody.

Can you check this file wc-admin-functions.php to make sure there is no extra space at the start of the file that's causing the error.
