Your LimeSurvey version: LimeSurvey 3.0
Own server or LimeSurvey hosting: 
Theme: test_theme
==================
Hello! I am trying to activate the option to save the timings but I cannot see the option under "Notifications&Data". 
 

It does not say that I cannot change the option specifically but I also cannot see the option to change it.

Once I read that if the survey is anonymized, timings cannot be saved. But it is also written on my survey that "Responses to this survey are NOT anonymized.
It is presented group by group."

I will appreciate it if you can help. 
 

This can be activated when your survey is not yet active, since databsse columns need to be reserved for it.

If you can: de-activate the survey, adjust the settings and activate again.

And update your application: version 3.0 is very, very old. The current versions are 3.27 and 5.2
