Multiple Issues with new site

Site: noblegassystems.com

Hi, I purchased the Highend theme back in January for a project that got tabled until now so I just started working with the theme for the site. It will be a simple one page site for the time being. I uploaded demo files and worked with an existing page (Contact) from the demo. Here are the problems/adjustments that I can’t seem to figure out:

1. I want the sticky header to have a transparent white background overlaying the site content instead of the gray/black overlay. I can’t figure out where to set this.

2. I selected that I wanted the header widget area with phone number and email address but it is not showing up. Is this possible while still maintaining the transparent overlay of the logo and nav over the image/video?

3. The map is not showing up. I entered new coordinates and also tried adding a new row with a google map and it’s still not showing up. It says to looks at the Javascript Console–not familiar with what that is or where to find it.

4. I would like the copyright info at the bottom but not the footer widget area. I deleted the widgets but there is still a black row showing up before the copyright block at the bottom. Also can not seem to change the color of the copyright block.

I will send my login credentials privately.
Thanks You!
