Stuck on checkout_shipping - blank page

[Best Price Accessori]

Hi,

On my site, When I checkout, it gets stuck on https://www.bestpriceaccessories.com...ckout_shipping. When you click the button a blank page comes up.

How do I fix it?

[02-Jan-2009 18:53:11] PHP Warning: Cannot modify header information - headers already sent by (output started at ......includes/modules/shipping/zones.php:270) in ....includes/functions/functions_general.php on line 44


Thats the error message. Any ideas guys? I'm lost.

I'd reload the file:
/includes/modules/shipping/zones.php

sounds like it is damage or corrupt ...

Usually that error means that you have space(s) or blank line(s) after the closing php bracket ?> and php will error on that ...

However, that file has a lot more than 270 lines so it makes me suspect that the file is bad ...
