<?php
 
// only applies when SearchWP is active
function my_searchwp_live_search_get_search_form_config)() {
  return 'my_config';
}
 
add_filter( 'searchwp_live_search_get_search_form_config', 'my_searchwp_live_search_get_search_form_config' );

There's an error in the function declaration, right?

Shouldn't it be: my_searchwp_live_search_get_search_form_config()

Cheers.

You are absolutely right and I have no idea how your comment went under my radar since May. Really sorry about that and thank you!

funny, I come across this 4 years later :-D
there's still the same typo :-)
