Map Disappeared

Question 1.
the map disappeared from GD Home, while it is added in the widget “GD Home Top Section”
1A. What could be the reason for that?
We will need to check your site for that. Please post your URL and WP admin details in a private reply so we can have a look.

1B. Is there a way to set what to be displayed in that GD Home page in the map and the results below or it just show ALL of the entries all the time?
The GD Home Page will display all listings [but depending on widgets you use etc].

Question 2.
2A. What is the way (trough shortcode?) to have similar pages as GD Home but with specific search results. For example to create a page named “PAGE 1” that would display a MAP and RESULTS below it the same way they appear in GD Home page, but only filtered by some criteria?
Every location has its own page, and every category, and custom post type etc.
There are also search pages.
I suggest you review https://wpgeodirectory.com/docs/layout/#directory
and add these shortcodes to a test page to get all the links to the automated GD pages:

[gd_location_tab_switcher]
[gd_advanced_search]
[gd_login_box]
[gd_cpt_categories]
[gd_location_switcher]

2B. More specific – we need search results based on CONTINENTS, what is the best way to achieve this?
Every country has its own page, but not continents.

Should we add a tag for every entry on which continent it is or this can be automated? Should we perform search results based on manually listing all of the countries of that specific continent (is this possible?)
See above.
You could use tags or a custom field, eg a SELECT custom field that contains a list of continents.

Question 3.
3A. Any documentation on how to make GeoDirectory multilingual using WPML?

3B. How to MANUALLY duplicate all the entries that don’t have translation (ONLY THEM) to propagate to all other languages (so they appear on search results, otherwise they wouldn’t appear (!))
Look in the sidebar when adding or editing the listing.

3C. Any idea/suggestion how to do that AUTOMATICALY (trough a hook/plugin or whatever) – so when there is a new entry submitted by a client, it is automatically duplicated to all other languages as well that are defined in the system (for example if one submits an entry while he was in the German language), but the site has English as well, the entry to have in BOTH languages.
WPML cannot automatically translate.

Thanks
