Hello,

Please add following given code in functions.php file of your child theme to change the phrase ‘Tour Details’.

	$output ['excerpt_text'] = 'Open a Blog';
  	return $output;

}

add_filter("travel_ultimate_default_theme_options","wp_travel_customize_text");

You can replace ‘Open a Blog’ with your desired text.

Hope this helps.
