Hi

We need to see where the issue lies. Can you follow the guide to make a Shortcode Display Results search type? It won’t look so pretty, but will make testing to find the problem easier:

https://www.designsandcode.com/documentation/search-filter-pro/search-results/using-a-shortcode/

With our Shortcode method, in the documentation link I gave you, is the guide to customising.

Once you have a copy of the results.php file in a search-filter sub-folder of your theme, you can edit that file, like this (leave the PHP comments at the top outside and before this code):

global $searchandfilter;
$sf_current_query = $searchandfilter->get(1024)->current_query();
if ((!$sf_current_query->is_filtered())&&($sf_current_query->get_search_term()=="")) {
  echo '<div>Nothing to see here folks!</div>'; 
} else {
  // the results.php PHP code here
}
