Google plus un bouton ne fonctionne pas (Google plus une erreur de bouton)

Question

J'ai installé Google plus un bouton sur mon site.

Quand je (ou quelqu'un d'autre) clique sur le bouton +1, il ajoute au compteur pendant 5 secondes, puis apparaît d'exclamation rouge. "

Answer 1

Make sure the page is accessible to Google (i.e. it's not behind a firewall, it's a staging server, etc)

Answer 2

If your site or page is blocked with an htaccess password-protected file then Google can't see it, and it won't let you Plus-One.

Answer 3

The same problem happens when you're developping under a localhost, you have to be on a distant server to have it work properly.
