Hi
Did you enable Login switch on template parameters (see features tab)?
About the quickstart version, it can be very helpful in 2 ways. Or building a brand new website or for those who have already a site built, you can install a local server like XAMPP (i.e.) and take easily experience with the template demo.
We have a quickstart video tutorial for Pulse template quickstart installation, and it's explained how to get, install and configurate XAMPP server. It's easy, believe me.
Check it
After XAMPP installation on your computer, the process of installing the quickstart version of The World News template is exactly the same.
Anyway, if you still have problem to display the login switcher, please send me administrator access to:
