Hi Julius,
First of all, the VPS slider will not show until you upload the template in an online hosting server. This is because, it’s loading via a server side script.
If you want to review the template in a local PC (offline), then you need to use a local server like Wamp or xampp.
By the way, we are on a vacation and unable to responding to support questions till September 6, 2017
Best Regards,
