Error when updating plugins by FTP “Unable to locate WordPress Content directory (wp-content).”

I ended up using code from this post on WordPress.org

Place this into my wp-config.php file

if(is_admin()) {
    add_filter('filesystem_method', create_function('$a', 'return "direct";' ));
    define( 'FS_CHMOD_DIR', 0751 );
}
