Can anyone tell me what this message means...

I am trying a test checkout of an order. After I choose the delivery method, I click the button to go to step 2, and I get a blank page that just has the following on it:


Warning: Cannot modify header information - headers already sent by (output started at /home/content/b/e/s/bestpizza/html/menu/includes/languages/english/modules/shipping/flat.php:53) in /home/content/b/e/s/bestpizza/html/menu/includes/functions/functions_general.php on line 44

Here's the URL of the site, if you want it, but you won't be able to get the error unless you set up an account: www.bestpizzainphilly.net/menu/

Click the tutorials/FAQ link at the top of the page. Enter "headers sent" in the search box or look in the Errors and troubleshooting category.

Awesome! That totally handled it.

Weird that I had like 4 different files that had extra lines at the end of them. Don't know if I did that or if they came that way. I had been editing some files (but not the bottom of them).

Thanks.

What are you editing your files with? Control Panel file editors are notorious for adding spaces at the beginning or end of php files. A plain text editor is recommended.

I'm using Dreamweaver 8.

What do mean by "control panel file editors"?
