    Hi,

    I’ve recently upgragde to ver 2.1 and on the System Status tab/page I now see 5 lines which state…

    Warning: Invalid argument supplied for foreach() in c:\xampp\htdocs\index.php on line 197

    Is this a problem?

    Also, I notice that my hourly and daily aggregated data does are not populated since the upgrade…only raw data. Could this be related to the problem above?

    Thanks,

    Anthony

    Sounds like a problem with the databases. Try to create a new global and local database in the settings/database and then an initial population with data with a dummy_poll
