I can not post on G+, it always returns the following error:

******************************
Array ( [pgID] => [isPosted] => 0 [pDate] => 2014-03-28 09:55:56 [Error] => WP_Error Object ( [errors] => Array ( [http_request_failed] => Array ( [0] => URL indicata non valida. ) ) [error_data] => Array ( ) ) – ERROR IMG Upl )
*****************************

the plugin is updated to the latest version!

Thank
