How do I change the first line of the Order Confirmation e-mail?

How/Where do I change the first line (Order Confirmation from <store name>) of the Order Confirmation e-mail?

What are you wanting to change?

I would like to change the verbage of the first line - Order Confirmation from <store name>. I found (I think) the code in classes/order.php and I made a change and uploaded it to classes/classic/order.php but it didn't seem to work.

Ok, If I upload the file to it's original location the change works. If I put it under the classic folder it does not. Are the files under classes overridden like all of the other files?

Are the files under classes overridden like all of the other files?

No, they are not overriden like the templates and languages. Make a note so that you can reapply your changes when you upgrade.

When changing a file that doesn't use overrides, I usually create an override folder anyway and keep a copy of the changed file in it. Zen Cart won't use it, but it'll be there when I upgrade/update and I can use it to make the same changes to the new file.
