  • I could be wrong, but I believe that is_multi_author() is a function introduced in WordPress 3.2.

    It’s trivial to add this to /wp-content/themes/twentyeleven/functions.php

    function is_multi_author() {
      global $wpdb;
      $rows = (array) $wpdb->get_col("SELECT DISTINCT post_author FROM $wpdb->posts WHERE post_type = 'post' AND post_status = 'publish' LIMIT 2");
      $is_multi_author = 1 < count( $rows ) ? 1 : 0;
      return (bool) $is_multi_author;
    }

    Where does this code go? Should it replace the existing code? I have tried various options, but no joy currently.

    why don’t you upgrade to wp3.2?

    generally, it would be added into functions.php of your theme;
    however, i would not advise this, as you are going to get another error message when you later update.

    Thanks for the posts. I was having this problem as well, went to the dash, found the link to update and it solved the problem. 🙂
