Placing an order as a 'guest' in PS version 1.3.1.1

[applecart_girl]

Hi there,

 

I'm currently using Prestashop 1.3.1.1 - & loving it :-)

 

Can anyone tell me how I can change the settings so that a 'guest' may complete their order without having to 'creat an account'?

 

A friend of mine is running a newer version and has an option to change this setting, however I don't see anything in mine.

 

Do I need to change the coding to allow this?

 

Thanks in advance! :-)
