Whoops - Major Malfunction

While trying to change some text from Table Rate to Shipping I wiped out the checkout function. Now when I add an item to the cart and proceed to checkout I get this:

Warning: Cannot modify header information - headers already sent by (output started at /home/oldsa4/public_html/public_html/includes/languages/english/modules/shipping/table.php:57) in /home/oldsa4/public_html/public_html/includes/functions/functions_general.php on line 44

I went back and thought I changed it back to TABLE RATE but get the same result. Any help is greatly appreciated since the checkout is now down.

Thanks,

Jack

I can't seem to figure out how to edit my post but the result of my actions in my post have disabled my checkout completely. Sure could use some help.

Checked out your link and the offending pages but could find nothing wrong. No extra spaces or missing text.

Got it. After I re-read your link I understood where the space after P?> was and removed it. Many thanks.
