Are you using our shortcode display results method? If so, edit the results.php file to use code like this:
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 {
// your template archive code/loop OR results.php code here
}
Change 1024 to the ID number of your form (from the form shortcode).
Make sure you are working on a copy of the results.php file in a search-filter sub-folder of your theme/child theme folder, and not the original in our plugin template folder.
