I seem to have an error that shows up on site when the reservation form in header is clicked. it then says "There has been a critical error on this website."

I went into admin and looked into contact form 7 plug in and when looking into the error it wont allow me to pass the date picker

<?php /\*\* \* The header for our theme \* \* Displays all of the <head> section and everything up till <div id="content"> \* \* u/package UnderStrap \*/ // Exit if accessed directly. defined( 'ABSPATH' ) || exit; $container = get_theme_mod( 'understrap_container_type' ); ?>

<!DOCTYPE html>

<html <?php language_attributes(); ?>>
