You need to change the source code and rebuild the payment method
So I have found this in a folder called "nopCommerce_1.7_Source Folder" that is outside the root folder on my computer, but I am unable to access this via ftp on the remote site.
Is there somewhere else I should be looking for it in the root folder?
What is the breadcrumb trail please?
