Login in menu

Edit the cook-pro/cook-pro.php file located in the plugins directory and find the below code which you can remove it

// Adds login logout to the admin menu
if ( 'on' !== get_option( 'rcp_login_link' ) ) {
	add_filter( 'wp_nav_menu_items', 'cookpro_add_login_logout_link', 10, 2 );
	function cookpro_add_login_logout_link( $items, $args ) {
		ob_start();
		wp_loginout( 'index.php' );
		$loginoutlink = ob_get_contents();
		ob_end_clean();
		$items .= '<li>' . $loginoutlink . '</li>';
		return $items;
	}
}

Yes, you have to but maybe in the future, we will consider adding a feature to disable or enable the login from the menu.
