why is this not overriding?

I am under the understanding that I am supposed to make a custom_template folder wherever I see a "classic" folder correct? Then if I make changes to .php files I am supposed to copy them into the custom_template folder right?

I'm asking because making changes to:
store/includes/custom_template/shipping/zones.php does nothing but making changes to: store/includes/modules/shipping/zones.php does something.

So why is it still reading the core file when I made the override and set it in the admin etc.. Is my path wrong?

Please help.

store/includes/modules/shipping/ doesn't have a 'classic' folder in it - and so it isn't an override-able folder. :smile:

custom_template folders are created at the locations where the classic folder is.

What you attempted to do is create a shipping folder fully outside of whare it exists. If there was a a classic folder under shipping...this is where the override folder would be created.

This might work:
/includes/modules/custom/shipping/zones.php

Have similar settings for other functions.

Just a Post Script to what website Rob suggested:

As there is not a "classic" folder inside of "shipping" these are not available to override...

I suggest that you make a copy, rename the orig with the extention .orig; make your edits to the copy and load to the original location...

Keep a log of these core edits so that prior to an upgrade you can preserve any file that also has a .orig copy there.
