We would need to see your site, so can you post your URL and admin details in a private reply please.

You have this in your stylesheet:

.sidebar .entry-header, .sidebar .entry-content, .sidebar .entry-summary, .sidebar .entry-meta {
    max-width: 1040px;
    padding: 0 376px 0 60px; 
}

Change the 376 to 60 or play with the numbers until happy.
I changed it for you, but that is where you can adjust it.
We strongly recommend to use a child theme: http://codex.wordpress.org/Child_Themes

1. Set the map width to 1040px in the map widget of the GD Top section.
2. Header right widget is not made for such big banner, adjust with CSS.
3. Set the content width of the GD Home section to 67% instead of 63%.

#1: There might be a setting in Genesis for that too, but you can add this to your CSS:

.entry-header {display: none}

This should assist too: https://wpgeodirectory.com/docs/customizing-your-style/

#2: Add this CSS:

.geodir-search input[type="button"] {width: inherit}

#3:

.entry-content ul {margin-left: 0}

#4:

.geodir_category_list_view li.gridview_onefourth {width: calc(25% - 24px);}

#5: Change the number to suit:

.site-inner {margin-top: 50px;}

#6: Listing preview is not a page you should add there, it will only show something when a user is submitting a listing and they want to preview, before submission.
The location page has nothing because you have not added any widgets:

#7: Without being able to register as a user, I cannot see the Add Listing page.

#8: We would need an admin account to have a look at that, you can post that in a private reply.

#9: If things are not taking effect, you might need to refresh and turn of any caching plugin you are using. Or you might not be looking at the right spot. If you can be more specific, we should be able to help.

#10: Widget heading background color:

.geodir_list_heading {background: none repeat scroll 0% 0% blue;}

Text in that heading:

.geodir_list_heading h2 {color: white;}

#11: Create your own markers, or https://wpgeodirectory.com/docs/faqs/where-can-i-find-map-markers/

#12: How can i set it up so someone can do a search for a town name and only see and the paid items and categories for just that town area.?
Add the location switcher so visitors can navigate to a town, and then restrict popular post widgets to only paid listings (featured).

#13: Have a closer look at the documentation and search the forum, and for anything else, we are here for you.

You’re welcome

No, we haven’t done a thing 🙂
So I guess all is well now?

I am pretty sure you cannot use dots or brackets, and probably there is a max length as well.
Try a shorter name and let us know how you went.

I’ll let Paolo answer you, but if you only have 8 locations, it would be simplest to just add links to each of the location using WP menu links, and disable the location switcher. Just a thought …
