Changing fields titles in the frontend form

Hi, additonally, you can change the labels using adverts_form_load filter

add_filter( "adverts_form_load", "customize_adverts_add" );
function customize_adverts_add( $form ) {
  if( $form['name'] != "advert" ) {
    return $form;
  }
  foreach( $form["field"] as $key => $field ) {
    if( $field["name"] == "adverts_price" ) {
        $form["field"][$key]["label"] = "Fee";
    }
    if( $field["name"] == "adverts_location" ) {
        $form["field"][$key]["label"] = "Place";
    }
  }
  return $form;
}

This code you can place in your theme functions.php file, or create a new plugin and add it there, other field names you can find here https://github.com/simpliko/wpadverts-snippets/blob/master/customize-adverts-add/customize-adverts-add.php
