Warning: Undefined property:…

  • Hi
    The admin page of the plugin shows at the top
    “Warning: Undefined property: WP_Post_Type::$kwayy_active in …/wp-content/plugins/kwayy-html-sitemap/kwayy-html-sitemap.php on line 303”
    I would like to keep the plugin, it does exactly what I need! Can I fix that?
    Thanks in advance!
