    Since my update to 3.6 it is not possible to update or add any plugins.
    I can't even update to WP 3.8

    This is the message I receive:

    Update WordPress

    Downloading update from http://wordpress.org/wordpress-3.8-new-bundled.zip…

    Unpacking the update…

    Fatal error: Call to undefined function mbstring_binary_safe_encoding() in /data/sites/web/triskalcharmscom/www/wp-admin/includes/class-wp-filesystem-direct.php on line 62

    Try re-uploading all files & folders - except the root wp-config.php & .htaccess files and the the wp-content folder - from a fresh download of WordPress 3.6. Make sure that you delete the old copies of files & folder before uploading the new ones.

    Thank you esmi, after this message I googled the code and found another post with the same problem (couldn't find it through the search of the forum here).
    They referred to this page : http://codex.wordpress.org/Updating_WordPress#Manual_Update

    I was afraid to re-install it manually but it worked and have 3.8 now!
    Thank you again
