No, you can only have one template for “Listings”.
You should be able to use conditional functions, depending on exactly what you want to achieve. This should get you on the right path: https://wpgeodirectory.com/support/topic/hide-tabs-in-custom-post-type-2/page/2/#post-25090

Oops, now I see. Add this to your CSS

#main {
max-width: 1130px;
margin: 0 auto;
}

Do you have at least one category and one listing in those CPTs?
Give us a URL and WP admin details if you need more help.

“When you say: You would have to make sure that all your references are relative instead of absolute, they should not have a reference to a domain name.
Where do I have to do that?”

You cannot really. You can only have one domain. You can do a redirect, but not a park.

I suggest adjusting your map size then, that should fix it.
Increase the height or decrease the width.

Post your login details in a private message if you want us to have a look.

You should have a template for your post view pages, which is part of your theme.
GD should not take that over.
If you have a widget area on that page, add a GD map to it.

A bit difficult to comment any further without a URL and your WP admin details. Post them in a private message if you need us to look.

Only a warning, just suppress it, see
