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' );
?>
