How to enable SSL ?

I have upgraded nopCommerce version 1.9 to 2.1 and did what it took to make it work.
Last thing I can't figure out is how to enable SSL use...  There was an option in version 1.9 but it is now gone...

You can enable it from the Web.config file.
In the appSettings section you need to set the UseSSL to True:

<appSettings>
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
    <add key="UseSSL" value="true" />


Hope this helps!
