    Hello.

    Please, help me.

    I have a warning during the backup process every day:
    "WARNING: call_user_func_array() expects parameter 1 to be a valid callback, function 'woocommerce_demo_store' not found or invalid function name"

    Before this warning there are such strings (sorry for russian):
    [02-Июн-2014 03:02:55] Сжатие файлов с использованием ZipArchive. Пожалуйста, будьте терпеливы это может занять некоторое время.
    [02-Июн-2014 03:03:20] Перезапуск через 28 сек.
    [02-Июн-2014 03:03:21] Undefined index: wt_movet
    [02-Июн-2014 03:03:21] Undefined index: woo_enable_lightbox
    [02-Июн-2014 03:03:21] Trying to get property of non-object

    [02-Июн-2014 03:03:49] Undefined index: wt_movet

    As i can understand it is related to plugin WooCommerce, but i can't understand if it is a real problem.

    What this warning means? How can i fix it? Is my backups full and working?

    No that are not critical Problems. That are Messages of Plugins and Themes of third persons. You can aus the pluginautors to fixing the Undefined indexes.

    The call_user_func_array messsage is a result of a add_action() call with a function that not exists. that can come from a theme or plugin.
