Inserendo l'oggetto social network barra addthis - pulsanti 'condividi', quando richiedo la validazione W3C mi da questo errore:

Line 288, Column 119: Bad value http://s7.addthis.com/js/300/addthis_widget.js#pubid=IIS Caminiti-Trimarchi for attribute src on element script: Illegal character in fragment: not a URL code point.…s7.addthis.com/js/300/addthis_widget.js#pubid=IIS Caminiti-Trimarchi"></script>

Syntax of URL:Any URL. For example: /hello, #canvas, or http://example.org/ Characters should be represented in NFC and spaces should be escaped as  .

Potete aiutarmi?
