[galaxy-dev] Where to add Account activation

I was reading the link: https://wiki.galaxyproject.org/Admin/UserAccounts I wonder where should I add the following line of code in the file universe_wsgi.ini user_activation_on = True I tried adding at the end of the code. I also tried to add in the [app: main] However, it is not functioning. Best Regards, Danielle Furtado.
