Can't edit on front end of Vantage, header unclickable
I am a designer who is customizing a Wordpress theme for my client. They have purchased Vantage, installed it, then turned it over to me. But when I go into Appearance >Customize the entire header is unresponsive; none of the buttons are clickable. The search bar, the logo to take me home, etc. I tried going outside the installer and see, but when I'm just viewing the page outside of Wordpress, it still does not work. I don't know if this is an installation problem, but also clicking buttons (i.e. changing a background color) doesn't change in real time either. I click a button and nothing happens, nothing is loading and nothing changes.
Also, can somebody explain to me the whole "Kitchen Sink" Foundation Framework? I thought it was a plugin you installed to get all those buttons but from what I've seen in the forums, it's actually just HTML you paste in the main code? Is there truly no other easy way to use that framework? I would appreciate any type of help, because out of 4 directory themes we look at, this one seems the strangest in format. The fact you can't mass change the font family and have to manually change it in CSS is maddening to me. Let me know if you need any screenshot to help facilitate the areas I'm talking about.
