    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:

    Downloading update from…

    Unpacking the update…

    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 :

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