    Hello there @jaavu, I hope you’re well today!

    The plugin you installed is more than 4 years old and is not compatible with new WordPress versions.

    You will have to login to your site via FTP and manually delete the plugin from wp-content/plugins folder.

    I hope that helps!

    Cheers,

    Ari.

    And this is wp-debug on site http://thothieunhi.trenmang.org/ :

    please guide me .

    With subsite , how can my single users backup and restore their database ?

    All of the above debug info you posted is simply notices and warning, nothing that would cause any issue.

    There is however this on the debug info of http://thothieunhi.trenmang.org/ :

    Fatal error: Call to a member function register_sitemap() on a non-object in /home/trenmang/public_html/wp-content/plugins/jdevalk-Google-News-Sitemap-f77b10c/xml-news-sitemap-class.php on line 28

    That can cause white screens etc.

    The problem is with the Google News Sitempa plugin on wp-content/plugins/jdevalk-Google-News-Sitemap-f77b10c/

    If you delete that plugin you should be ok.

    With subsite , how can my single users backup and restore their database ?

    They can’t… Only superadmins can do that. So you’ll have to do it for them if you wish.

    Cheers,

    Ari.
