Re: # Web Analytics Date format must be: YYYY-MM-DD, or 'today' or 'yesterday' or any keyword supported by the strtotime function (see http://php.net/strtotime for more information):

It seems a problem with the database data... Trying with several URL parameters (idSite=1 ko, idSite=2 ok) I have managed to login, but now... it shows no data! (I has data since march 5th) It looks like the `piwik_site` `idsite` were being modified or some other key.
