Shipping not working getting TEXT_NO_SHIPPING_AVAILABLE

Hi i have just installed the latest version of zencart and am having trouble with the shipping.

I have installed zencart lots of times and never had this problem.

the problem is no matter what shipping i set up in admin when i go to a product page and click estimate shipping cost it displays

TEXT_NO_SHIPPING_AVAILABLE
TEXT_NO_SHIPPING_AVAILABLE

were the shipping cost should be. please see attached image

does anyone no why this will be happening?? like i said i have installed zencart lots of times and never seen this problem,

please help thanks

When a "Constant" is displayed, there is a "Bad" or corrupt or possibly a mis edited file at the root of the issue
Use developers tool kit to locate the files that contain that constant

I have used the developers tool kit to find the files that contain TEXT_NO_SHIPPING_AVAILABLE and replaced them, but this didnt help.

I also tried replacing all the files again. but this didnt work. Could something have happened when it was installed?

I dont really want to re install the database but if i have to i will. could this be the problem??

please let me know thanks

That wouldn't be in the database. It's defined here:

includes/languages/english/checkout_shipping.php

so that should be where the problem is. Do you have a copy of that file in your custom template folder?

There is nothing wrong with that file and no i dont have a copy of it in my template folder here is a copy of the includes/languages/english/checkout_shipping.php file
