Hi all,
I also changed in all order_conf.html - Files I could find on Serverside the "hallo..." Text to "Guten Tag".
But in the order-confirmation Mail I get an ugly "hallo".
Presta Cache is deletet, var/cache folder too.
There are any other places, like a little joke from developer-side, I need to check?
Any hidden/secrete folder server side I need to change too?
First I tried this:
https://belvg.com/blog/how-to-edit-email-templates-in-prestashop-1-7.html
But it didn't work.
Someone here who can help?
Presta, I love you.
:::: EDIT::::::
Now the "child-folder" did it!!!
Puh...
if you want to change the text: Upload the file you need in your child. There, change the text!
I dont know why it first didnt work. But now, its working 
:::: EDIT::::::
yours,
DAniel
