I have found posts on this for earlier versions of nopcommerce but can't find how to change this text in v2.1. Content Management > Localization must have had a name change
You're absolutely right. Forgot to localize it. You need source code package in order to do it. Open \src\Plugins\Nop.Plugin.Payments.PayPalStandard\Views\PaymentPayPalStandard\PaymentInfo.cshtml file and manually update the statement
A probably silly question. Where will I find the \src\Plugins\... folder? I don't find it on ftp site.
You'll need to download the source code version of nopCommerce. The plugins are compiled into dll's and the file you need to change is stored in one of the plugin dll's. Once you have the source code, you will make the change in the file specified by Andrei and then you will need to recompile and redeploy the web application.
You can download the source code version of 2.2 here:
