PHP Warning with SEO widget in piwik 2.0.3



I’ve just installed Piwik 2.03 on my server. As far as I know, everything works fine, except the SEO Notation widget, which displays the following message :

I use Piwik in French, so “Connexion termin?e par expiration du d?lai d’attente” should be translated in english with “Connexion closed because of waiting delay expired”, or something like it.

It may be an issue with my server, so juste tell me if you need more data to understand this issue.

Thank you for your help, and for Piwik : it’s a great software.
