    After installation and activation I go to the menu item wp-admin/admin.php?page=simplybook-integration and get an error
    Undefined variable $page

    if (!$page) {
    $page = isset($_GET['sbpage']) ? sanitize_text_field($_GET['sbpage']) : 'main';
    }

    Solution

    if (!isset($page)) {
    $page = isset($_GET['sbpage']) ? sanitize_text_field($_GET['sbpage']) : 'main';
    }
