Dear Sandras,

We are extremely sorry for delay response. I personally goes to your queries and your site and try to solve your queries. Here are solutions for your queries.

1. To fix menu problem, the child theme code be as follows

<?php
// Exit if accessed directly
if ( !defined( 'ABSPATH' ) ) exit;

function my_theme_enqueue_styles() {

	$parent_style = 'event-star-style'; // This is 'evemt-star-style' theme

	wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css',array('event-star-googleapis','bootstrap','font-awesome','slick','magnific-popup') );
	wp_enqueue_style( 'child-style',
		get_stylesheet_directory_uri() . '/style.css',
		array( $parent_style ),
		wp_get_theme()->get('Version')
	);
}
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
remove_filter('widget_text_content', 'wpautop');

This is important wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css',array('event-star-googleapis','bootstrap','font-awesome','slick','magnific-popup') );

2. We would like to suggest you to use 1280*853 for the front page feature images

Let us know if you have further queries.
