You have to be consistent in using references to States etc.
Probably a good idea to create a listing first so you see what the API expects.
GD uses the latitudes and longitudes to locate things on the map, but when organising your data it also takes into account how things are named.

DO NOT CHANGE ANY LOCATIONS
All listings in that location will be deleted if you do that, see note on the edit page: “Post will be deleted if both city and map marker position has been changed.”

Just MERGE bad ones with the correct ones.
Create a correct one before merging if you do not have a correct one.

I did not suggest normal select control only, but the search auto-completer AND the full list of current locations.
I think that is how it used to be in the earlier versions.

Are you using Payment plugin? Have a look at the settings there, they might have been set to 1 image allowed only?

Add this code to /GDF_Child/functions.php:

/**
 * Register our new widget area.
 *
 */
function goldroo_widgets_init() {

	register_sidebar( array(
		'name' => 'Center for Review',
		'id' => 'goldroo_widget_1',
		'before_widget' => '<div id="goldroo_widget_1">',
		'after_widget' => '</div>',
		'before_title' => '<h2 class="rounded">',
		'after_title' => '</h2>',
	) );
}
add_action( 'widgets_init', 'goldroo_widgets_init' );

Then add this to your /GDF_Child/page-for-review.php after
<?php // end article header ?>

<?php dynamic_sidebar( 'goldroo_widget_1' ); ?>

Then go to Appearance > Widgets > and add GD Search to Center for Review new widget area.

If you are using the new template for the review page, you then should have the search added to that page where you wanted it.

You might have to adjust some of the CSS.

You need to clean up your locations, you have numerous “all” locations, and numerous double ones, like Flushing in NY and New York.

Do that first and then try again.
I think your system can’t figure out the difference between NY and New York.

Yes, categories without any listings will not show.
A category will show the listing count in the particular search (location or CTP).

It does not show the categories that are viewed, it will show all categories of a CTP if you navigate to one CTP only, or all the categories if you navigate to a location.
See my test site to have a play: http://goldroo.net/

You need to copy a page (page.php) from
/wp-content/themes/GeoDirectory_framework
to
/wp-content/themes/GDF_child
and rename it to something like
page-for-review.php

Then go to Appearance > Editor and edit that page.

You can then add

<?php
/*
Template Name: My Review Page
*/
?>

to the top of that page.
That will add it to the list of templates you cna use for your pages.
You will then need to adjust that template as per
