OK, I have re installed the mod as mentionned above, and it works perfectly now .

I don't know why it didn't work in the first place ! Maybe I did it more properly (i used to leave for example the new order.php file and order_OLD.php file in the same directory, maybe this is why all went wrong)

I hope this will help anyone who gets into the same error message !
