I can´t enable the Quick Actions drop-down menu and the reminders under Self Service Portal Settings

I don´t find where I can enable the Quick Actions drop-down menu and the reminders under Self Service Portal Settings. In the administrator guide says that there is an option to enable the reminders. The guide says "If you wish to show all your tasks as reminders to the requesters then select ' Yes' radio button else select ' No' option. The reminders will be shown in the home page." but I do not saw this option in the page.
 
Someone help me telling me how I can enable the Quick Actions drop-down menu and the reminders under Self Service Portal Settings in the systems
 
Thanks in advance for your help
