Fatal error message on 3.7.1 upgrade

    @jeffycu

    When trying to update to 3.7.1 I get the following message:

    Downloading update from http://wordpress.org/wordpress-3.7.1-no-content.zip…
    Unpacking the update…

    Fatal error: Call to undefined function mbstring_binary_safe_encoding() in /home/content/17/11440517/html/wp-admin/includes/class-wp-filesystem-direct.php on line 62

    I also see this on the WordPress updates page:

    Plugins

    Your plugins are all up to date.

    Themes

    Your themes are all up to date.

    Fatal error: Call to undefined function wp_get_translation_updates() in /home/content/17/11440517/html/wp-admin/update-core.php on line 333

    I would really appreciate some advice on how to resolve this.

    Thank you.
