Hide the location links everywhere

Hi,

The easiest way to do this is to use Mapbox (How to get a Mapbox API key - HivePress Help Center), but the Mapbox API key will still be required.
Unfortunately, it is not possible to add these locations manually.

If you mean hiding maps, you can try this CSS snippet:

.hp-map {
  display: none !important;
}

To hide location in Add Listing form, please refer to this topic Can you edit the attributes from account/listings?

Also, to hide the location as shown on your screenshot, please try this CSS snippet:

.hp-listing__location {
	display: none;
}

Please note that it can require further customization.
If customizations are required for your site, please try customizing it using the collection of code snippets Search · user:hivepress · GitHub and other developer resources, or consider hiring someone for custom work https://fvrr.co/32e7LvY.
