Error at post indexer

There is something not right at the post indexer. When i open the page "new post" at http://members.socialnetworkersunited.com/wp-admin/post-new.php i get the next error:

Fatal error: Call to undefined function get_blog_status() in /home/socialnetw/domains/members.socialnetworkersunited.com/public_html/wp-content/plugins/post-indexer/post-indexer.php on line 225

    Hello and Welcome to WPMUdev forums!

    The error is indicating your blog status is causing an issue.

    If you can check your Privacy settings for your site to ensure that you are allowing indexing.

    If that doesn't help then you can reply with some more info about what other plugins you are using and we can try to sort it out

    Best,

    Kimberly
